List Keymap: Fix backspace behavior when selection is not collapsed

[juraj98]

Changes Overview

Fixes #4368

Implementation Approach

I figured that just checking if selection's to and from doesn't match, default backspace behavior will result in expected behavior. So I added check to handleBackspace.ts.

Testing Done

N/A

Verification Steps

1. Start development environment and navigate to /preview/Extensions/ListKeymap.
2. Create a list with one or multiple list items, and paragraph underneath.
3. Select all and hit backspace.

If you created list with one list item there will be no error in console. If you created list with multiple list items, the behavior will be as expected. Compare this with previous behavior either of tiptap's develop or live example
