Previously if a worker's state machine had already transitioned into the 'listening' state when it received the message enabling the debugger, the worker would never enable its debugger. Change the logic to allow the 'listening' as a valid state for enabling the debugger. Fixes nodejs#6440
unref one superfluous timer (as the test suite already has a global timeout), and improve the state machine to iterate the messages more reliably. Ultimately make the test complete more quickly.

the debugger.
Fixes #6440
Also improve the test that covers this mechanism.
