Commit message mentions don't work in first branch push

Summary

When pushing to a new branch the commit messages are not parsed for issue numbers/links.

Steps to reproduce

git checkout -b bugfix
git commit -m "This fixes issue #55"
git push -u origin bugfix

Expected behavior

Issue 55 should have a mention of the commit in it's activity feed

Possible fixes

The project's activity feed only shows an entry for pushing a new branch and no mention of the commit(s). I'm guessing the logic to check for commit mentions is only on pushing commit activities.
