Reports

Other bugs fixed

8127 Most-circulated items report doesn't work when limited by library

This fixes some of the filters for the "Most-circulated items" report so that using limits (the Limits section with "Limit to" and "By") now works.

Previously some options for "By" (such as Library and Week) generated an error message or there were no results (when results were expected).
