Description :
In ACDQueue.ts,
When there is no queue available on asterisk, onQueueSummary never gets executed. It directly calls onQueueSummaryComplete
Because result.queueSummary never got initialised, result is undefined.
This causes getQueueDetails fails as it assumes that there will be a valid queue summary.

To fix this, set result.queueSummary to empty array if it does not already exist in onQueueSummaryComplete of ACDQueue.ts
