Scramble 0.13 moved the collected resource type of resource collections
to a different template slot, which broke the custom paginated resource
collection extension and the API docs export. Scramble now infers
paginated responses natively, so the extension, the marker interface and
the @return annotations that overrode the inference are removed.
Scramble 0.13 also documents closure routes, so the API fallback routes
are moved to a controller that is excluded from the docs.
Add a test that exports the API docs.
