[ToDo] ShowToDo error when no ListType

[ssss141414]

What project is affected?

ToDo skill

What language is this in?

All

What happens?

Some utterance will trigger ShowToDo, but no ListType entity:
Remind me to review my Planner tasks.
Display task notes.
These will cause an error.

Because there are default ListType setting code in Mark/ Delete dialog:
state.ListType = state.ListType ?? ToDoStrings.ToDo;
(Or AskListType step) to avoid this bug. I think ShowToDo should also do this.

What are the steps to reproduce this issue?

What were you expecting to happen?

Can you share any logs, error output, etc.?

Any screenshots or additional context?
