Importing a question as the first question keeps the tutorial arrows on

[chrissolanilla]

Description

When creating a new This or That widget and importing an existing widget, the guided arrows (e.g., pick answer type) get stuck on the imported questions if you do not complete the first blank question before importing. This prevents interaction with text fields like feedback and question editing.

how to reproduce

1. Create or have an existing "This or That" widget with some questions.
2. Start creating a new "This or That" widget.
3. Without creating a question, import an existing widget.
4. Delete the initial blank question (created by default).
5. Observe that the guided arrows remain active on the imported questions.

I am not sure exactly how often this type of issue would actually arise, but it should be a relatively simple to fix assuming all that is needed is to check if a complete question exists and then disabling the arrows.
