Core prematurely sends success for DeleteInteractionChoiceSet

[Jack-Byrne]

Bug Report

SDL Core deletes UI Interaction Choice set before response received from HMI for successfully deleting the corresponding VR Command. Core also responds success to mobile before knowing the status of the VR.DeleteCommand response. If the VR.DeleteCommand was unsuccessful then the mobile will no longer be synchronized with the state of the HMI.

Reproduction Steps

Change HMI to not respond to VR.DeleteCommand
Create Interaction choice set
Delete Interaction choice set

Expected Behavior

Mobile should receive error from core (Timed out or generic error)

Observed Behavior

Mobile receives success from core.
