mail_daemon: auto check message was leaked, send immediately.

* BMessageRunner does not take ownership of the message.
* Instead of waiting through the complete interval, we send an auto check
  message immediately after launch (or whenever else the timer is being
  started).
* Added constant instead of referring to 'moto' for the auto check message.
