[IMP] voip: remove grouping by initial in softphone contacts listing
    
    This commit keeps the alphabetical / phone sort, but no useless groups
    anymore. Idea: it was only to have a "pretty" listing but it will
    prevent more advanced sorting to make sense in the future (e.g. showing
    most called contacts first). This also simply improves Owl performance
    as a bonus.

[IMP] voip: use AddressBook for keypad "more" searches
    
    Before this commit, the keypad component was implementing its own
    contact searches, with unsorted results. Indeed, with the demo data,
    search "m" would for example have "Mitchell Admin" first, because it
    was loaded first by discuss for the presence status, then the rest of
    the contacts having "m" in their name.
    
    The "more" keypad search view now uses the AddressBook component,
    sharing the UI and its features.
    
    The keypad "more" view had 2 extra differences though:
    - Search match highlighting
    - T9 searches
    
    Those 2 features are now added in the AddressBook component.
    
    Bonus: while in the "more" keypad view, you can now edit the search.

[IMP] voip: (really) allow contact search by email
    
    Before this commit, when a contact was searched in the softphone,
    contacts were loaded in the store based on their name, phone... and
    email. But then the softphone filtered the store contacts by name and
    phone... but not email. This lead to this weird behavior:
    
    - Have a contact zzz with email yyy@example.com
    - Have 50 contacts alphabetically before zzz
    - Search "y" => You don't see zzz
    - Remove the "y" search
    => You see 13 contacts + zzz (because it was loaded before)... if you
       scroll, contacts will appears between the 13 contacts and zzz.
    
    Now, you will at least see zzz during the "y" search making the last
    step less confusing, and allowing to actually take profit of the search
    by email that is already done loading-wise.

Note that this is also a first step towards fixing problems introduced
by [1] a long time ago, when the softphone used the Store to gather the
loaded contacts, while before the tab components themselves were in
charge of loading and displaying the loaded contacts.

Step to reproduce:
- install l10n_co_dian and pos
- open pos and click on create a new partner from partner list
- enter name ex. "temp", identification number, click on form
- notice a `refresh icon` is visible: click on it.

Observation:
- the dialog is closed and partner is selected with "temp" name

Expected:
- with valid government credentials and a valid identification number,
the refresh action should also update the partner data on the POS side

Cause:
- the refresh button triggers the `button_l10n_co_dian_refresh_data` action,
which fetches the legal name and email from the government service
- although the backend record is correctly updated, the new values are not
immediately synchronized with the POS
- when the refresh button is clicked, editPartner() first triggers
`web_save` using the temporary "temp" name and immediately reads the
partner data afterward
- the refresh action executes later and updates the contact with the fetched
legal information, but the POS is not aware of these subsequent changes

Fix:
- read the data again if there is any update caused by this action.
- this is done by overriding `afterExecuteActionButton` of FormController class
