Fix for amqplib connection unhappy path timeout

[lamchakchan]

Description

• For both the createConnection and createChannel logic, the unhappy path when the amqplib returns with err populated, the semaphore counter for the respective resource was not reset causing future connection and channel resolutions to hang.
• When a channnel + queue is consumed and the queue is being deleted, a null payload is send down the consume RPC call. Logic needed to be put in place to account for null payloads to not act.
• Also adjusted the test name.
