Ghost messages

This might be the whole cause of missing deliveries that is troubling Kontalk users (and even me).
I found messages being saved again and again (thus refreshing the expiration date) from January 2017 (!!!!) to existing and valid users. What is happening here??

Ghost messages appear to be saved with full JIDs having non-existing resources. The resource is the device ID, since it isn't connected, Tigase sends the message to offline storage again (and sends a copy to the bare JID, but that doesn't fix the issue itself).

Anyway the problem here is mainly waste of server resources. I need to find a way to properly store the timestamp to the initial value, and not to the time of each storage.

To a more close look at the database, there are messages with a bare JID in to and they are not delivered nonetheless. That is not valid behavior.
