Since the inspector does not longer hold on strongly to Script objects after they were collected by V8, this test was relying on the GC to not collect the scripts too eagerly in case where nothing else holds on to the script. So explicitly adding a global object property assignment here in those cases to ensure that the Script is kept alive.
