[FIX] account_edi: check fiscal period for an EDI cancellation

Steps to reproduce:
    - install a localization which uses the account_edi module;
    - define Lock date for the fiscal period;
    - choose an invoice which was sent before this date;
    - click on the "REQUEST EDI CANCELLATION" button.

Issue:
    We try to cancel the EDI document despite exceeding the fiscal period.

Cause:
	The verification of the fiscal period is done when clicking on the "RESET TO DRAFT" button which, in the flow, is after the request for cancellation of the EDI document.

Solution:
    Make a verification of the fiscal period when clicking on the "REQUEST EDI CANCELLATION" button.
