Fix the bug that queries UsageStatsService for locked users

In addition to the bug fix, this also changes the user lifecycle callbacks People Service is using:

1) onUserUnlocking() -> onUserUnlocked()
2) onUserStopped() -> onUserStopping()

The user lifecycle callback changes are based on a recent callback API
change in ag/10396717. This change will make the service run safer: it
avoids performing queries on locked users.
