ref the listener for the duration of this function, since emitting

	* backend/ebook/e-book-listener.c (e_book_listener_check_queue):
	ref the listener for the duration of this function, since emitting
	"responses_queued" may cause it to be unreffed by its EBook in
	some cases, which could cause the second response_queue check to
	look at garbage data if it got destroyed.
	(e_book_listener_destroy): Call g_source_remove if idle_id is set.
