test(puter-js): fail credential lookups until the relay hits one

The reconnect test made the next credential lookup fail once, but the
SDK's own socket.io connection could take that failure before the
relay's reconnect attempt did, so the relay never saw a failed lookup
and the test failed in CI. Lookups now fail until the relay has refused
an attempt on one, then recover.
