Force unity8 usage-mode to Staged

The current version of unity8 in Vivid has the 'usage-mode' set to 'Automatic', meaning it tries to detect whether it's running on a phone or a desktop. Because Autopilot exposes a fake mouse it tricks unity8 into thinking it's running in 'Windowed' mode. Most Autopilot tests are just not ready to run like this so naturally fail. Until this is resolved in Autopilot (or Unity8) we need to workaround it by forcing the usage mode to 'Staged' (which was the default before). As a matter of courtesy we also reset the usage mode to what it was before the test run.
