Camera2 always crashes after Permission Dialog

[andhie]

1. Build and run the Demo app
2. When the Permission dialog pops up, just accept it
3. Demo app crashes immediately
   --- or ---
4. Revoke the Permission from Setting and re-enter the app,
5. after the Permission Rationale dialog is shown, just accept the Permission Dialog
6. watch it crash again.
