Fix bug with the handling of empty query.

JBoss sends empty queries for checking connections. We decided to replace
the empty query with dummy SELECT command not to affect load balance.
Empty query has been replaced with dummy DELETE command till now.
Note: The dummy command is not sent to backends.
See the following thread for more details:
