Disables all WindowManagerAppTest as they are flakey

My first attempt was reverted as disabling the only test in a harness
caused problems with the script that runs the tests.

My early attempt didn't trigger try runs because script that
determines when to run apptests needed to be updated. I'm doing that
here too.
