`where` mutates original

[AlexParamonov]

where method should not do any mutation. New object have to be returned back.

so far hotfixed with:

JsonApiClient::Query::Builder.prepend(
  Module.new do
    def where(conditions = {})
      dup.tap do |clone|
        clone.instance_variable_set(:@path_params, @path_params.merge(conditions.slice(*klass.prefix_params)))
        clone.instance_variable_set(:@filters, @filters.merge(conditions.except(*klass.prefix_params)))
      end
    end
  end
)
