...but dev.bootcomplete flag is not set
Rework things to address a few issues I found:
- When the activity goes idle, the way we were handling finishing the
boot there was calling finishBooting() with the lock held, but it
shouldn't. We now dispatch that and turning on the screen together
in a separate message.
- Make sure we don't try to start the home activity until we have
reached the point of the system being ready and mBooting being set.
This ensures we don't do any work prematurely.
