[SQL] Kill dangerous trailing space in query string

MD5 of query strings in `createQueryTest` calls are used to generate golden files, leaving trailing spaces there can be really dangerous. Got bitten by this while working on #2616: my "smart" IDE automatically removed a trailing space and makes Jenkins fail.

(Really should add "no trailing space" to our coding style guidelines!)
