To reproduce
============
- create a payment term with Balance of 3 months and a percent with 50 as value
- create a vendor bill using this payment term
- try to register a payment, the amount is not showing
Problem
=======
the amount field would be invisible if the Group Payment check box is checked,
and in this case it should be checked because it's one deadline.
Solution
========
the problem comes from the fact that the compute method that will check or uncheck
the group payment field, is called twice in same compute process but we only execute it
once because the record is protected and that's how ORM is expected to work to avoid infinite loops.
to solve the issue, `group_payment` was removed from `_get_batches` because it's not necessary.
