TypeError when moving an element

Sentry Issue: ARKINDEX-FRONTEND-AJZ

TypeError: undefined has no properties

1. Open an element
2. Move the element to another folder
3. With enough luck, you will get this error.

This error can occur quite randomly because this is a race condition between the HeaderActions' re-rendering and the store mutations called by an asynchronous store action.
