define set_to_display as empty string when undefined #2399

Without this, if you go to the Library Browser, Set Definition Files button, and just click to view problems with no set selected, you get a perl error because of line 553 (the debug line) using an undefined string. It seems like if the string is undefined, it's OK to define it as '' in the previous line to avoid this. And likewise with viewing problems from "Course Sets".

This is so minor, I will go ahead and merge it.
