Added listener for input_filter links

- Fixes issue reported on the apigility-users list: REST creation was resulting
  in an error during rendering. Problem was due to the composed input_filter
  relational link, as it was missing the controller_service_name property. Added
  a renderResource listener that corrects the situation.
Update RPC input_filter links as well

- RPC services can also compose input_filter links, so ensure they can
  be injected properly, too.
Merge branch 'hotfix/input_filter_links'

Fixes issue reported on list about exception raised on creation of services.
Issue was result of trying to render the input_filter link relation, as the
controller_service_name is not in the route matches during service creation.
Added a renderResource listener to inject the controller_service_name into the
route parameters.
