GeolocationBrowserTest: only put bubble in test mode when needed

GeolocationBrowserTest: only put bubble in test mode when needed

The GeolocationBrowserTest runs both with and without permission
bubbles. There's no need to set the permission bubble view into test
mode if the permission bubble isn't being used. This adds an if-check.
