Query.One + Filter fix

This release fixes the behavior of Query.One in conjunction with filters (reported in #248). Previously, it could return ErrNotFound if the first result page was empty; now, it will iterate through pages until it finds a result. The old behavior can be retained by adding a SearchLimit or with RequestLimit(1).

Thank you @dharkness for reporting the issue.
