[FIX] crm: make crm.team.write work in batch again

When `_synchronize_alias` was introduced into crm.team.write, the write
method become incompatible with batch writes because
`_synchronize_alias` assumes `self` is a recordset of length 1 and
performs attribute accesses directly on self, this makes the __get__
crash because it performs a `self.ensure_one()`

With this commit, crm.team.write will iterate over the self recordset
and call `_synchronize_alias` on every record of the recordset.

This also solves a uninstallation problem in sale_crm because a write is
performed on crm.team in an uninstall_hook.
