Currently phabricator hard codes the refs paths.

Please hard code refs/changes/ and refs/meta/ please.

https://github.com/phacility/phabricator/blob/master/src/applications/diffusion/query/lowlevel/DiffusionLowLevelGitRefQuery.php#L43

Since trying to do that in a file won't override it or add the new red paths.
