Fix sandbox setconfig and associated test

Fix sandbox setconfig and associated test

The sandbox setconfig test was taking over a second--a pretty clear indication that it was waiting on the fake delta stream rather than a direct response.  Investigation revealed that the sandbox method was incorrectly using the ASYNCOP helper rather than the OP helper.  This small branch fixes the setconfig problem and adjusts the tests.  The test is very fast now (not yellow or red in the mocha output).
