Check extras to determine if the call is cross sim

- when the call is terminated, instead of displaying
  cellular internet, the UI briefly displays wifi call,
  even though the cross sim extras are present. This occurs
  because the ImsCall object is cleared as part of the clean-up
- If available, check the updated extras instead of querying
  ImsCall to confirm if it is a cross sim call
