Fix onStatusBarTouchEvent_withoutSceneFlag_onSameDisplayTouch_handlesInput

Test was failing on specific builds due to a HSUM issue. The userId didn't match the calling id in the test, which stopped the expected method from being called. Fix is to just mock the user Id to always match the calling user Id.
