Correctly activate windows even if they're not in the iconic state (#32)

Browse source 
* exwm.el (exwm--on-ClientMessage): Handle the case where a window is
hidden but not iconic. This code would previously error in some cases
because a buffer wouldn't have an active window even when it was not in
the iconic state, likely due to a focus race somewhere.
