Fixed to_compact_hash not working on Chat and Array object

[araishikeiwai]

For an object message of type Telegram::Bot::Types::Message, if you call

message.to_compact_hash

The chat and entities attribute don't get converted to a hash.

I fixed it by making Chat class inherit Base (because the condition on calling to_compact_hash in the method is only checking whether the class inherits Base or not). Another alternative is by adding additional inherited class in the condition (Telegram::Bot::Types::Compactable)

Also, arrays of compactables don't get converted properly, I setup recursive method to convert arrays too.
