Entering text into empty first block on new document triggers 'block-changed' event rather than 'block-created'

If a new editor is instantiated and no initial data is provided, editorjs creates an empty block in which the cursor is set. If the user starts typing in this block, editorjs triggers the event `block-changed`.

Steps to reproduce:
1. Initialise an empty editorjs instance
2. Provide an `onChange` function and listen to it
4. Start typing in the first empty block
5. Check the console

Here's a demo implementation: https://6246d3405682fb7683a8b9be--editorjs-bug.netlify.app

Expected behavior:
Editors should trigger the event `block-created` because before the first input no block exists that could be updated.
