Exception thrown when undoing link with a non-collapsed selection

📝 Provide detailed reproduction steps (if any)

👀 The issue should get fixed by #7462 👀

1. Open https://ckeditor.com/docs/ckeditor5/22.0.0/examples/builds/classic-editor.html
2. Focus the editor.
3. Remove all the content.
4. Type few words.
5. Select the last word.
6. Use link command with ctrl/cmd + k
7. Press ctrl/cmd + z to trigger undo

✔️ Expected result

At least exception is not thrown (I don't think that pressing ctrl+z with link plugin should invoke undo in a first place).

❌ Actual result

An exception is thrown:

snippet.js:4 Uncaught TypeError: Cannot read property 'is' of undefined

    at rt.on.priority (snippet.js:4)
    at rt.fire (snippet.js:4)

• Browser: Chrome (didn't check Safari)
• OS: Win10 (didn't check other)
• CKEditor version: v22.0.0
