fix(widgets): fixed-outbound-fail-error

COMPLETES #< AD-HOC >

This pull request addresses

• EPIC team reported an issue that was happening with the widgets.
• Whenever a user got the AgentOutboundFailed event, the widgets was not properly cleaning up the call and so the user was not able to do further outdials.
• Further triaging found that this was because the SDK was clearing the task object on receiving this event and hence subsequent wrapup was not being shown.

by making the following changes

• Now we simply emit TASK_REJECT on receiving the AgentOutboundFailed event and on subsequent events from the backend, we end task and show wrapup.
• Code was also added to ensure that rejecting the outdial event clears up the task and older flows remain unaffected.
• Other task clear ups also work.
