refs/starred-changes/ uses '/' to separate the sharded account ID from
the change ID, but refs/draft-comments/ uses '-'. Make the naming
consistent by using '/' in both cases. Using '/' has better
performance when looking up all refs that start with this prefix
because RefDirectory in jgit has explicit optimizations for the case
when the prefix ends with '/'.
