Do not pass events with no window to the findClient - windowEvent cascade 

If the eventWindow is none the check for InputIdMatchPredicate will find
a matching Client and pass the even through the windowEvent filter which
returns true for all not handled events and thus filters out all events
processed later on in KWin.

This explains why some events were eaten...
