The record `documents_hr_contract.documents_hr_documents_contracts` has `forcecreate=1` and there is a chain of dependency of these 3 records:

1. `documents_hr_contract.documents_hr_documents_contracts` [--> 2.](https://github.com/odoo/enterprise/blob/17.0/documents_hr_contract/data/documents_tag_data.xml#L12)
2. `documents_hr.documents_hr_documents`                                 [--> 3.](https://github.com/odoo/enterprise/blob/17.0/documents_hr/data/documents_facet_data.xml#L7)
3. `documents_hr.documents_hr_folder`

But for the latter 2 records **forcecreate=0**. All of these records are set `noupdate=1`. That is why during upgrade the latter 2 records will be skipped from creation if they are missing in db, but it will try to create the 1st one because of that forcecrete=1. This will cause dependency issue if the db is missing the other 2 records.

For solving the issue we set `forcecreate=1` to the latter 2 records.

**Steps to reproduce:**
1. Install modules documents_hr, documents_hr_contract in version `16.0`
2. Delete the document facet `documents_hr.documents_hr_documents`
3. Delete the document folder `documents_hr.documents_hr_folder`
4. Try to upgrade to `17.0`

You will see similar traceback to this:

Issue:
======
The whole content is removed when deleting empty line

Steps to reproduce the issue:
=============================
- Go to to-do
- Add some text in the first line
- Keep the second line empty
- Add some text in the third line
- Select some prefix of the third line with the second line too
- delete
- All the content before the empty line is removed

Origin of the issue:
====================
We are in this case:
	`<p>abc</p>`
	`<p>[<br></p>`
	`<p>d]ef</p>`

- The `startContainer` in this case is the `p` element and not the `br` so
we will not insert the `zws` node inside the `p`.
- We assign `next` as the text node containing `ef`
- Extract content will remove all the content inside the second `p`
  element and will be like this
	`<p>abc</p>`
	`<p></p>`
	`<p>ef</p>`
- We set selection at the end of the `start` node `<p>[]</p>`so it's like we set
  the selection in  `<p>[]ef</p>` so now `getRange` will return
  `startContainer=endContainer=textNode(ef)` so `joinWith` is
  equal to next which is the text node containing `ef`
- In the join `while` loop , we have `doJoin=true`, `next` always
  truthy, `next.previousSibling` will never be equal to `joinWith`
  since `next=joinWith` so it will keep deleting until we don't
  have anymore previousSiblings which is basically remove everything
  before.

Note: This doesn't happen in the case the second line has some text
because we insert a `zws` before the text node.

Solution:
=========
Since we apply `fillEmpty` on `start` after extracting the content, we
need to get the range after we insert the `br` again to make sure we
get the correct `startContainer` and `endContainter`.
