Fix 1-time crash when launching 2.16 from notification

didBecomeActive is too late in the case of launching from a
notification.

Also, start tracking when app setup is complete, and prevent certain
actions from occurring in that case. Eventually we'll enqueue these
actions rather than ignoring them, but we'll want to do more testing
before releasing that. In the meanwhile, if the environment isn't setup
at this point, a crash would be eminent anyway.
