Fix Additional Payment div tag issue in Accordion
Based on this discussion here on pull 29448 we need to modify the divs to ensure that the Check is placed inside the Payment Details (rather than outside).
This problem existed in previous versions before. The issue lies in templates/CRM/Contribute/Form/AdditionalPayment.tpl
and can be seen below.
@nicol comments:
This closing div closes the crm-accordion-body too soon so the check field is outside the border. This should be removed, and the one below (line 106) brought back.
