Improvements for stored procedures and binded queries

It was a huge improvement to solve the problem with a “second run” in stored procedures and binded queries.  Sometimes there was an incorrect behavior because of “over-prepared” nodes. There was a workaround with “EXECUTE” statement (which is actually developed  to prepare any SQL statement and execute one from another SQL statement). So now this workaround could be omitted.
