Turn off cloud sync if we have managed profiles

UserManager#getUserProfiles > 1 implies managed
profile.

Workflow:
- Disable sync prefs
- Execute an async task to check for managed profile; if
  managed profile is found, remove the sync prefs. If not, enable
  the preference;
- Move the logging pref from Advanced to Account & Privacy.
