Follow up to #19079, which made test names fully qualified. This fixes tests that now-redundant information in their test names. For example here's a fully qualified test name before the changes in this commit: "priority_queue.test.std.PriorityQueue: shrinkAndFree" and the same test's name after the changes in this commit: "priority_queue.test.shrinkAndFree"
