markedRange is not cleared when multi stage input finished.

[hstdt]

What happened?

When I'm dealing with textViewDidChange

It's not the same as what UITextView delegate did.

What are the steps to reproduce?

Finish a multi-stage input.

What is the expected behavior?

When shouldChangeText(in range: NSRange, replacementText text: String) or textViewDidChange(_ textView: TextView) called, textView.markedTextRange should be nil if multi-stage input finished.

Thanks for opening the issue. I'm working on a refactored version of Runestone and believe that this issue will be solved in that.
