l10n runbot builds are all failing when running at least one test depending of AccountTestCommon because it:
- doesn't create a sandboxed testing environnement to manage the multi-currency, multi-company, the default company's currency, the exchange rates...
- doesn't setup a testing user then all tests are done using the superuser.
- doesn't provide a fully setup chart of accounts: exchange difference journal is not set, accounts have bad types, etc...
- is run sometimes at-install.
--task: 2296213
- Split compute function in res.partner into 4 functions as they no more share the same dependencies
- removed dead constraint from 'membership.membership_line' model. That constraint checks if the invoice's date
is greater than membership line's date but the membership line is created before the draft invoice is created
(and that too without date set), hence it can't be raised.(Though, it can be raised if we check it on 'state' field).
