Update transient_for when a new window appears 

When we manage the transient before the main window, the client object's
.transient_for property would stay nil. This happens because the property points
to a window which we don't know (yet) and thus is ignored.

Fix this by remembering the value of WM_TRANSIENT_FOR and checking in
client_manage() if the new client is the "missing window we did not find
before".
