Remove set description icon from ProblemSets page.

The set description is available on the ProblemSet page, and no
longer needs to be a tooltip on the ProblemSets page. This removes
the icon complete.

This is an alternative to openwebwork#2946 instead of trying to make the
tooltip accessible and available on touchscreens, just remove it
in favor of showing it only on the ProblemSet page.
