Handle IoT test case names in pwhalen's namespace
    
    We have a check when finding result rows that the row contains
    something that looks like a test case name; this is breaking on
    the new IoT matrix where several of the test cases live in
    @pwhalen 's namespace and don't follow the usual naming policy.
    This updates that check to also allow test case names following
    that pattern.
