The `__git_pseudoref_exists ()` helper function back to git-rev-parse(1) in case the reftable backend is in use. This is not in the same spirit as the simple existence check that the "files" backend does though, because there we only check for the pseudo-ref to exist with `test -f`. With git-rev-parse(1) we not only check for existence, but also verify that the pseudo-ref resolves to an object, which may not be the case when the pseudo-ref points to an unborn branch. Fix this issue by using `git show-ref --exists` instead. Note that we do not have to silence stdout anymore as git-show-ref(1) will not print anything.
