Re-fix for my 07-18 not-quite-fix.

	* backend/ebook/e-book-listener.c: Add a "stopped" flag like
	EBookViewListener.
	(e_book_listener_check_queue): Don't emit signals if the listener
	is stopped.
	(e_book_listener_queue_generic_response, etc): Don't queue
	responses if the listener is stopped.
	(e_book_listener_stop): Flush the queue and stop queue/emitting
	further responses.

	* backend/ebook/e-book.c (e_book_unload_uri): Revert the previous
	change and call e_book_listener_stop() instead.

	* backend/ebook/e-book-view-listener.c
	(e_book_view_listener_stop): When removing an idle handler, unref
	the listener as well, since e_book_view_listener_queue_response
	will have ref'ed it.
