Fix/events client errors

[makelicious]

Client had some open warnings and errors. Some changes caused form to crash. There is a possibility that mismatch between toolkit versions made it possible.

1. Prevent form from crashing due managing state at two levels. Create method for reading state with less re-renders
2. Clean up missing key warning, add rule to avoid it in the future.

Oops! Looks like you forgot to update the changelog. When updating CHANGELOG.md, please consider the following:

• Changelog is read by country implementors who might not always be familiar with all technical details of OpenCRVS. Keep language high-level, user friendly and avoid technical references to internals.
• Answer "What's new?", "Why was the change made?" and "Why should I care?" for each change.
• If it's a breaking change, include a migration guide answering "What do I need to do to upgrade?".

Seems like the form values are flickering between {} and <initial value object>. Fixed after applying these changes
