Make acts_as_resource_controller's base_url method be compatible with custom Rails config.relative_url_root

[masda70]

Right now, if the Rails app uses a custom relative_url_root, the JSONAPI link builder will use the wrong base url to build its links.

In my own app, I set for instance config.relative_url_root = '/api', and this change broke my app. I had to override the ResourceController's base_url method to fix this.

  def base_url
    @base_url ||= request.protocol + request.host_with_port + self.config.relative_url_root
  end

lib/jsonapi/acts_as_resource_controller.rb could use something like that as new default.

self.config.relative_url_root can be nil, and then the + will throw an error. First check for nil.

👍 I'm seeing this as well, in that a show method, customized as per the example, in a JSONAPI::ResourceController creates a json with relative url's missing the protocol and the host_with_port; whereas the default jsons have full absolute urls.
