Comment (by dgoulet):

 After a discussion on IRC with nickm, we agree on a solution. This issue
 only happens if `EntryNodes` has only '''one''' single entry so we should
 trigger a warning in that case if you are an HS and add a comment in the
 `EntryNodes` documentation about this issue with one node.

 Will try to provide a patch soon.
