[FIX] account: wrong sequence number reset for refund type moves

In case a yearly sequence is set for out_invoice/in_invoice types and if we set
a monthly sequence on the corresponding out_refund/in_refund type, we will not be
able to validate the refund the next month as it will be wrongly identified as a
yearly sequence. We should include the move type when retrieving the last
sequence name instead.
