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
