This pull request addresses

• Currently in the CC SDK, we do not directly support consultTransfer to a queue with a dialNumber
• We also are overriding certain task data on queue consult, this is causing issues.

by making the following changes

• Extract the destinationType from the backend event data so we can ascertain if it is a dial number or basic queue consultTransfer.
• Fixed the overriding of TaskData on AGENT_CONSULTING event as this was redundant and interfering with everything.

Tested With Arun
