[0/1] Fix error message in git-show-ref(1) --exists

Message

References can validly contain forward slashes in their name. With the ref files
backend, these are stored as a directory tree. This means when you look up a
reference, you might find a directory where you expected a file.

This causes the option --exists, recently added to git-show-ref(1), to return
the following error:

    error: failed to look up reference: Is a directory

Other backends, like reftables, might store refs with forward slashes
differently. So they will not encounter the same error.

To make the error consistent across refs backend implementations, and to be more
clear to user, hide the error about having found a directory as a generic error:

    error: reference does not exist

  builtin/show-ref: treat directory directory as non-existing in
    --exists
