Fix failing tests around prefixes.

There were commented out tests for prefixes + controller routes. Using
a prefix should create more specific route names that match earlier
preventing names like `users:_action` from matching.

* Fix up name generation for plugin/prefixes with 0 as a name.
* Remove bad Controller test for prefix.
* Remove duplicate route prefix test.
