[Michael Hall]

Check that at least one plenary room exists before trying to use it

Overview
========
Viewing the schedule without a plenary room throws an error.

Details
=======
Part of the schedule display code attempts to force plenary slots into plenary rooms only, but this throws an error if no plenary room has been defined. This fix keeps plenary slots off the schedule until a plenary room is defined.
