Clean up lifecycle in MobileNetworkSettings
To avoid double registering, which prevent potential issues and could
improve latency.
Since DashboardFragment already supported register lifecycle
automatically for the controllers bound by XML which implements
androidx.lifecycle.Lifecycle, so doing a cleanup to prevent register
lifecycle event manually (doubling).
Bug: 149338098
Test: temporarily add logging to make sure the lifecycle method is
called and only called once
