Code review comment for lp:~cjwatson/turnip/auto-create-repository

I think I was misled by your comment on https://code.launchpad.net/~cjwatson/launchpad/git-namespace/+merge/248995 where you said "We might also be able to get away with doing this on the first repository access" into thinking that we could do part of it on the first access *in turnip*, and didn't think properly about the state requirements. Fair enough; I'll withdraw this MP, and include GitHostingClient again in Launchpad when I get far enough up the stack to have the XML-RPC service code.
