Properly append preload / includes args on Merger
Couldn't find other way to get the association name from a given class
other than looping through `reflect_on_all_associations` reflections ..
Noticed this one while looking at this example:
```ruby
class Product < ActiveRecord::Base
has_many :variants
has_many :translations
end
class Translation < ActiveRecord::Base
belongs_to :product
end
class Variant < ActiveRecord::Base
belongs_to :product
end
class BugTest < Minitest::Test
def test_merge_stuff
product = Product.create! name: 'huhu'
variant = Variant.create! product_id: product.id
Translation.create! locale: 'en', product_id: product.id
product_relation = Product.all
.preload(:translations)
.joins(:translations)
.merge(Translation.where(locale: 'en'))
.where(name: 'huhu')
assert_equal variant, Variant.joins(:product).merge(product_relation).first
end
end
```
