`l10n_es_edi_sii` requires `Client.bind` as well as `_binding_options` in the service returned by this `bind` call.

```py
serv = client.bind('siiService', service_name)
if company.l10n_es_edi_test_env and connection_vals.get('test_url'):
    serv._binding_options['address'] = connection_vals['test_url']
```

Can be tested with a external l1On unit test,

Original PR description

Steps to reproduce:
-------------------
- create an appraisal for an employee;
- be the manager of the appraisal;

Issue:
------
It is not possible to edit feedback before saving it.

Cause:
------
The `accessible_employee_feedback` and `accessible_manager_feedback` fields are read only if `can_see_employee_publish` and `can_see_manager_publish` are equal to `False`.
These two fields depend on the `_compute_buttons_display` method, which will test whether the employees linked to the user are in the appraisal managers.

The following condition will never be true if the appraisal has not yet been saved:
```py
user_employees in appraisal.manager_ids
```
This is because manager_ids will be a `NewId` recordset.

Solution:
---------
It is necessary to compare ids and not records directly
because Model does not support equality between
existed records in database and virtual records.
