Don't run AllTraces in test 911 on CTS

AllTraces will (among other things) list every thread currently
running. Unfortunately this means it breaks every time anyone adds a
new thread to the app environment. This happens somewhat regularly so
instead of maintaining an every-growing list of ignored threads we
will instead just skip this bit of the test.
