Bruno Castro 6b3e9bc5c9 feat: Include ORM associations in CollectionDecorator (#845)
## Description
Include all QueryMethods from the ORM in CollectionDecorator. The default adapter is :active_record

* Why was this change required?
It was necessary to delegate or define a method of the ORM which you are using in your decorator to make an instance of CollectionDecorator able to call it.
* Is there something you aren't happy with or that needs extra attention?
In order to support other ORM associations, we'll need to write a method `allowed?` for each strategy at `lib/draper/query_methods/load_strategy.rb`

## Testing
1. Create a decorator for the model and its association
```ruby
class OrderHistoryDecorator < Draper::Decorator
  delegate_all
end

class OrderDecorator < Draper::Decorator
  delegate_all

  decorates_association :order_histories, with: OrderHistoryDecorator
end
```

2. Call any query method in the decorated instance
```ruby
pry(main)> Order.last.decorate.order_histories.includes(:user)
```
