breadCrumb override is ignored on a root route

[dguettler]

It looks like ember-crumbly is looking at the customers.index route for the override.
So if you define the override on customers.index it is correctly applied for both cases.

Ran into the same issue i noticed that in:

bread-crumbs.js

`_guessRoutePath(routeNames, name, index) {
const routes = routeNames.slice(0, index + 1);

if (routes.length === 1) {
  let path = `${name}.index`;

  return (this._lookupRoute(path)) ? path : name;
}

return routes.join('.');

},`

Removing the .index on the path seemed to fix my issue but i do not know why it was there in the first place or if it is truly needed

Also seeing this, weird that it requires the index, when the index could have it's own crumb. This is most certainly a bug.
