When mixed into AR model, and AR association with accepts_nested_attributes_for has a reject_if proc, the proc is never invoked

[evaniainbrooks]

Minimal example

class Product < ActiveRecord::Base
   include NestedAttributes

   belongs_to :store
   accepts_nested_attributes_for :store, reject_if: ->(_) { raise "This never raises" }
end

product = Product.new
product.update(store_attributes: { bicycles: {} })

I traced the issue down to the call_reject_if method redefinition inside NestedAttributes mix-in here:

https://github.com/DmitryTsepelev/store_model/blob/master/lib/store_model/nested_attributes.rb#L141

The parameters don't match the method parameters inside the ActiveRecord mix-in:

https://github.com/rails/rails/blob/dd8f7185faeca6ee968a6e9367f6d8601a83b8db/activerecord/lib/active_record/nested_attributes.rb#L598

Renaming the method in this gem to something else, like call_store_model_reject_if, fixes the issue.
