Ignore stopped state when becoming visible and ensuring configuration.

We normally don't ensure configuration for activities in the stopped
state since it doesn't make sense to be relaunching something that isn't
visible. However, if the activity is becoming visible, then ignore the
stopped state allowing the configuration to be ensured and the activity
relaunched if needed.
