Bug 1497219 - Rejecting PaymentRequest::API calls when the PaymentRequest is not in fully active document. r=baku PaymentRequest API is not supported when the PaymentRequest is not in the fully active document. Adding bool a PaymentRequest::InFullyActiveDocument() method to check if the PaymentRequest is in fully active document. This method should be called at the start of any PaymentRequest APIs. If the PaymentRequest is not in fully active document, ignoring the API call and throw the NS_ERROR_DOM_ABORT_ERR if needed.
