[FIX] account: fix self.id.origin in get_last_sequence()

When trying to customize Swiss invoice report with QR-Bill
through Studio an error was thrown because it tries to _compute_name()
on a dummy 'account.move' record with self.id=0.

This is part of a more general task in master around report customization
but it make sense to backport the fix in all stable versions.
