[FIX] hr_expense: Update payment states after moves updated

Issue

	- Configure bank journal to post at bank reconciliation
	- Create 2 expenses paid by company
	- Create a report for the two expenses
	  (make sure bank journal configured in the first step is used)
	- Submit, approve and post journal entries

	Error message : "You cannot modify a journal entry linked to
	a posted payment."

Cause

	Since the payment state of expenses lines is updated one by one
	in related move, the first expense had already a 'posted'
	state when updating second expense line, who go against
	_validate_move_modification validation.

Solution

	Update payments state only after updating all moves lines.
