Rewriter not initialized correctly when not selecting server-version upfront

[grtjn]

If you run ml new and forget to specify server-version, Roxy will ask, but if you pick 8, it still initializes with the wrong xqy rewriter. Luckily it auto-corrects at deploy, but it does print a warning.

Minor bug..

Cannot reproduce. It may have gotten wrong by hitting enter at a preceding question where it was unnecessary. That might have caused the server-version question to get kind of skipped, leaving things in a bit of an unclean state..

server-version could go wrong in combination with no-prompt option though..
