Fixed missing commit_id for non-perforce clients when posting a new review
Review Request #8006 — Created Feb. 26, 2016 and submitted
After 2cf7aaf, posting a review would only have a commit_id for scm clients that supported changesets. After the breaking commit, commit_id would always be set to changenum when posting a review, regardless of whether or not a changenum was found (impossible for git clients, for example).
Tested posting a review with a git client
