Change status string for "In test queue with no testers assigned" in the new test queue tables

[mcking65]

In the status column of the test run tables in the new test queue, when no testers are assigned, the status string is:

In test queue with no testers assigned.

That string is appropriate in the report status dialog, but on the test queue page is unnecessarily verbose and potentially confusing because the user is looking at the test queue. Change the status to:

No testers assigned

Note: make this change only on the test queue page; leave the this status string as is when displayed in the report status dialog.
