wl: a deactivate cannot hand the pending text back

40fd4ab was half right and the sway run said which half.  The compositor
does relay the commit when a client merely disabled its text input while
holding the focus -- that much was read correctly out of sway -- but the
client has stopped listening by then.  On the wire, in that order:

	-> zwp_text_input_v3.disable()
	-> zwp_text_input_v3.commit()
	<- zwp_text_input_v3.preedit_string("")
	<- zwp_text_input_v3.commit_string("가")
	<- zwp_text_input_v3.done()

and the entry unchanged.  GTK3 drops global->current at its own
focus-out, and any client that follows text-input-v3 does the same, since
events between disable and the next enable are to be ignored.  So the
composition is unrecoverable there, by no fault of ours, and the commit
was a request nobody could take.

The code goes back to what it was; the comment does not.  The old one
said the compositor drops the commit, which is true only when the focus
moved, and that half-truth is what invited the change.
