Task/435 loglib the messages 2

### Description
Finished the transformation of the log message texts into a more ordered manner.
Also, removed all LM_RE and LM_RVE.

This issue resolves issue #443 
Also, after this, very little left on the log feature (issue #435)

Now, the discussion on these messages can start ...

In this particular case, the called function is entitiesQuery (in MongoGlobal.cpp) and whenever entitiesQuery returns false, it reports a Database Error before it returns.
One more Database Error after the call doesn't really add any information.
