Security definition missing in Swagger JSON.

Thanks for providing this gem, it helped me a lot and I have something up and running.

During the process of setting everything up (Grape, WineBouncer, Swagger and SwaggerUI) I ran into the issue, that in the generated Swagger definition the "security" declaration for my secured methods are missing:

module API
  module V1
    class Me < API::V1::Base
      resource :me do
        desc "Return information of authenticated user"
        oauth2
        get do
          present UserRepresenter.prepare(resource_owner)
        end
      end
    end
  end
end

Is generating the following JSON:

"/api/v1/me": {
  "get": {
    "summary": "Return information of authenticated user",
    "description": "Return information of authenticated user",
    "produces": [
      "application/vnd.api+json"
    ],
    "responses": {
      "200": {
        "description": "Return information of authenticated user"
      }
    },
    "tags": [
      "me"
    ],
    "operationId": "getApiV1Me"
  }
},

When I add desc "Return information of authenticated user", security: [{ "oauth2": []}] to the definition of the description of the method, everything works fine, but I expected WineBounce would take care of that automatically, so I wouldn't need to declare it twice.

As Oauth2 definiton I have the following setup:

"securityDefinitions": {
  "oauth2": {
    "type": "oauth2",
    "description": "The API is secured by OAuth 2.0",
    "tokenUrl": "...",
    "authorizationUrl": "...",
    "flow": "password",
    "scope": []
  }
},

And I'm using the Swagger strategy:

WineBouncer.configure do |config|
  config.auth_strategy = :swagger
  config.define_resource_owner do
    User.find(doorkeeper_access_token.resource_owner_id) if doorkeeper_access_token
  end
end

I'm currently unsure if this is a bug like discussed in https://github.com/antek-drzewiecki/wine_bouncer/issues/32 or https://github.com/antek-drzewiecki/wine_bouncer/issues/51 or an error in my setup?

Would be great to get some feedback, because I tried a lot, but didn't found a proper setup.

Thanks for your time and support!
