undefined method `calculate_page_count' for nil:NilClass

https://github.com/cerebris/jsonapi-resources/blob/41df1475876dd7cfa3459e9cf0241a82e71c59c9/lib/jsonapi/processor.rb#L89

Configuration for JSONAPI http://jsonapi-resources.com/v0.8/guide/configuration.html

JSONAPI.configure do |config|

# :none, :offset, :paged, or a custom paginator name

config.default_paginator = :paged
config.default_page_size = 10
config.maximum_page_size = 50config.top_level_meta_include_record_count = true
config.top_level_meta_record_count_key = :record_count
config.top_level_meta_include_page_count = true
config.top_level_meta_page_count_key = :page_count
end

class ContactResource < BaseResource
attributes :name, :email

paginator :none
end

When paginator is set to :none in resource level, Then it shows undefined method `calculate_page_count' for nil:NilClass

solution:
https://github.com/cerebris/jsonapi-resources/blob/41df1475876dd7cfa3459e9cf0241a82e71c59c9/lib/jsonapi/processor.rb#L89

if (paginator && JSONAPI.configuration.top_level_meta_include_page_count && record_count)
page_count = paginator.calculate_page_count(record_count)
end

Start in lib/jsonapi/processor.rb at the referenced line and reproduce the configuration with a resource using paginator :none and page-count metadata enabled. Confirm the request no longer raises undefined method `calculate_page_count' for nil:NilClass and that the response metadata remains correct.
