focus: do not revert to another client when client is unfocused

This was a nice idea to fix most focus bugs at once. However, due to the
runtime of e many things can get "randomly" focused, for exmaple: volume
control on the frame, internal dialogs, config value screens when
grabbing for keys, widgets when they get created in a gadget. The list
is quite long. However, fixing all those little bugs is hard and partly
impossible as the behaviour is correct in the context of a toolkit, not
in the context of a compositor.

Long term we should split window-focus and canvas-focus from each other,
then bugs like these would not be a problem anymore.
