Title: verify that scrollfps cli argument app name is a supported app

If you pass in an app name that isn't supported as a scrollfps test, you get a cycle of 30 messages saying
"AssertionError: Failed to launch app with name ''"

which isn't very useful. This pr prints out a helpful message and quits before deploying the 30 test iterations.
