Reviewers

We occasionally get error emails when web crawlers load datagrids with
poorly-formatted query parameters. Our own links will never try to load
?sort=,, but crawlers sometimes do. This change fixes it to properly
handle the situation where we have a non-empty sort string (",") but do
have empty sort parameters.

Loaded a dashboard with ?sort=, and saw that the page loaded instead
of creating a crash.
