wayland: Flush text_input.done event after IM key event

Browse Source 
We set an idle to coalesce multiple IM events together, as the protocol
requires us to send them in one frame, and unfortunately there is no
idea about whether more IM events are upcoming.

One good hint though are key events generated from the IM, we want to
apply all IM changes before the key event is processed, so make it sure
that the .done event is flushed before the key event is handled.
