This originally comes form the ember-href-to helper and is one of those
errors that when I see it I think ... hmmm
This gives a little bit more of a clue as to what is wrong by logging
the route name you asked for plus the params you passed to it so you:
1. Have more help finding the href-to that is problematic in the
template/component
2. Can see all the parameters you passed (including a potential null
parameter for the thing you are missing)
