Comment 14 for bug 1889133

Here's another patch doing what Galen said in comment 12. I also made Current Item and Requested Item non-sortable for the time being since they were also throwing ugly errors.

One bit of weirdness - I had to remove [multiSortable]="true" from eg-grid. With that in place, the grid ignored the eg-grid-column [sortable]="false" settings entirely. Is there a better approach that allows multisortable to stay but still disable sorting in specific columns?
