[FIX] base, account: fix test for 2020

When `invoice_sequence_number_next` is set in [1], the move date is not
taken into account to find a corresponding `ir.sequence.date_range` in
[2]. We use the current date instead.

However, when the move is posted we use its date to find the
`ir.sequence.date_range` [3]. This leads to an inconsistency: we set
`invoice_sequence_number_next` on the `ir.sequence.date_range` of the
current date, but at posting we use the `ir.sequence.date_range` of the
move date.

The fix is to take into account the move date when we set
`invoice_sequence_number_next`.
