Filter should be provided in options hash when calling ActiveRelationResource.count

首先跟踪调用 ActiveRelationResource.count 的处理器路径，然后检查其自定义 records 方法如何接收第一个参数和选项哈希。检查相关的 count 和 records 测试，并在传递给 count 的过滤器可以通过选项哈希获得且不会破坏现有行为时，将该 issue 视为完成。

The filters are passed in from the processor as the first parameter in ActiveRelationResource.count. However they are not in the options hash, so if the custom records method relies on those they will not be available. From Gitter
