This prevents a MITM attack where attacker could
still access Git repository if any jobs were

If user unsubsrcribes from a resource that they no longer have
access to they should not be revealed the resource path, but be
redirected to app root instead.

the identity to the user.

This should fix: https://gitlab.com/gitlab-org/gitlab-ce/issues/56509
