Empty university author list breaks page

[jrmerz]

Corner case here, but if no university authors are specified (see isOtherUniversity flag), the query and page breaks here:

Followup the isOtherUniversity is a little off, it's just checking for FacultyMember which doesn't include staff. loop could use a little tlc as well:
