Change a few critical checks that were failing sometimes: - A few asserts were changed to wait_for_object_condition - A 15 second timeout was removed (default used instead) - Do a full scan at beginning of each test to clear any cached BSS's. The second test run was getting stale results and the RSSI values were not expected.
