- When installing an accounting l10n module, the method `try_loading_for_current_company`
is called and could cause a deadlock.
The deadlock is caused by the fact that if the installation is started
via a web request the code tries to retrieve the current user's
company by doing `request.env.user.company_id`.
This causes issues since the installation code has its own postgresql
cursor while calling `request.env.user.company_id` will create its own
cursor.
So two cursors exists for the same Odoo worker.
The installation cursor asks for a lock on `res_users` while the
second cursor (the request one) will try to read on `res_users` and
wait the first lock to be dropped.
The lock is never dropped since the python code isn't running anymore
waiting for the `request.env.user.company_id` to be completed.
Causing the deadlock.
To fix the issue, we avoid the creation/usage of a cursor created by
`requesŧ`.
So to retrieve the current user's company, we read the user id on the
request's session, then browse the `res.user` record with the
installation cusror.
