[IMP] repair: Prevent to Unlink Repair Orders if not draft

Before Commit:
-Current Functionality doesn't Restrict Unlink of Order Based on States.
-if we delete the invoice linked to repair order the state button of invoice
 still visible in reapir order and when we click on state button it open
 new draft invoice.

After Commit:
-Add Validation on Unlink the order based on State,link unlink order only
 on draft and cancel state.
-Always show the "cancel" button on repair orders.When the orders have been
 cancelled, only allow to delete them if there is no invoice linked, or if
 the invoice which is linked can be deleted (is still draft and has never
 been posted). If we are not in one of those conditions, raise the following
 error "You cannot delete a repair order which is linked to an invoice which
 has been posted once."
-Add wizard when cancelling a repair order which has a draft invoice linked.
