Weird deprecation warning

[JIucToyxuu]

I'm use representable(version 2.5) and this throws the deprecation warning:
[Representable] Mixing user and representable options is deprecated. Please provide your options via :user_options.
This happened when I' use #to_json method. I do short detective research code and see strange situation. Maybe this should be as is, but see really strange.

1. begin from call this - https://github.com/apotonick/representable/blob/v2.4.1/lib/representable/json.rb#L43-L45;
2. this will call #to_hash - https://github.com/apotonick/representable/blob/v2.4.1/lib/representable/hash.rb#L33-L40;
3. in process of execution, #to_hash will call method which will add _self parameter -https://github.com/apotonick/representable/blob/v2.4.1/lib/representable/hash/collection.rb#L22-L30;
4. for this call #Serialize method - https://github.com/apotonick/representable/blob/v2.4.1/lib/representable/serializer.rb#L38-L45;
5. result of call #Serialize - again call #to_hash, but with options which contain _self parameter.

So, this trigger deprecation warning - https://github.com/apotonick/representable/blob/v2.4.1/lib/representable/deprecations.rb#L13-L14

Hey, it's best to upgrade to 3.0 (which should be working without any code changes for you!) since the deprecations are a bit hairy.
