Added hostIdentifier to info output

Small change that adds the the hostIdentifier in the output to the info log when running queries.

Also, wraps the `DBHandle::getInstance()` call in a try block, an cause the `getHostIdentifier()` function to throw an error if it cant access the DB.
This was NOT removed. We kept this around purposefully. If there are latency spikes it's good to have an "about" time to check if multiple/single offending queries ran.
