Adding this log because it is useful to figure out how many services are attached when you call disable.

This is repeated in carAppLifecycleObserver.onStop, looks like it should be moved to a separate function.

there are still some slight differences like logs and the condition for if (attached)
think i prefer to let them continue to be separate, cover the issues with tests

Description
Found this issue while testing this #6233
mapboxNavigationis still valid after callingdetach. This means all calls tocurrent()will return non-null, and if you unregister an observer it can result detach calls after it has been disabled. It is expected, to have a single onDetached call per every onAttached.I separated this pull request from 6233 because it would definitely impact anyone using
detach.
