Don't call filterQuery twice #455

The following code calls filterQuery just to get the pagination. It then calls paramsToAdapter which calls filterQuery again.

Instead, that line should just use this.options.paginate. This may seem like a micro-optimization, but I am extending the filterQuery method in a way that may traverse/clone the query multiple times, even stuff like id: { $in: [...many ids] } will cause many loops/clones.
