Martin Gräßlin 48a6272916 [tests] Support a trasient window in the waylandclienttest
Main purpose is to reproduce a crash if the parent window gets
destroyed before the transient. For this the following key combo
can be used:
t: show transient
k: close parent window
q: quit application

This currently causes reliably a crash in Deleted::copyToDeleted for
the connect of the mainClients.
