This commit fixes some issues related to fetching assignee icons for
dashboards and workspace. The issue where an "undefined" message would
pop up when fetching test assignes is now also fixed in addition to a
previous fix for group assignes. A small bug that caused group assignees
to always return an empty set is now fixed, so they work properly now.
