Various minor changes

- AsynchronousLogin: call common permission methods through CommonService instead of PermissionsManager
- CommandManager: remove superfluous replacement of %p (handled by lazy tag replacer)
- Remove unused method in CommonService
- Create DebugSectionConsistencyTest
- SendMailSSL: Enable debug output if AuthMe log level is set to debug
- Add Utils#logAndSendMessage and replace existing, separate implementations
