fix: inaccessable PR commits breaks `git clone`

we cannot list PRs under refs/heads/pr/* unless we are sure the oids
are accessable on a git server as it will cause `git clone` to fail.

we now only  list PRs that are on accessable repo git servers under
refs/heads/pr/*.

we should be able to list them under under refs/pr/* as the clone
command only fetches refs in refs/heads so we will do this
seperately.
