Fix CUJ UiThread detection when only a SurfaceControl is provided

Most methods annotated with @UiThread were not actually running on the UI thread related to the CUJ (when its ui thread was different than the app main thread).

When deferred monitoring was true (the default case), everything was fine, as the "begin" method eventually goes to the choreographer, and is scheduled on the correct UI thread.

When deferred monitoring was true and only a surface was provided though, the "begin" method was being executed
