[dshokouhi]

Summary

Fixes the following sentry error that I was able to reproduce:

Basically added a conditional check: https://android.googlesource.com/platform/frameworks/base.git/+/master/services/core/java/com/android/server/notification/NotificationManagerService.java#3412

Not sure if we should print a logger for this, it seemed best to just skip the error unless we decide to notify the user.

For the record our default channel seems to be miscellaneous

Also fixes an incorrect variable in debug logs
