anyOf field incorrectly updating after change

[SuriGill]

Prerequisites

• I have read the documentation;
• In the case of a bug report, I understand that providing a SSCCE example is tremendously useful to the maintainers.
• [] Ideally, I'm providing a sample JSFiddle or a shared playground link demonstrating the issue.

Description

Since updating to react 16, the anyOf field doesn't correctly update after receiving props. It will override the selected option incorrectly. This can be resolved by migrating to the componentDidUpdate method instead of the componentWillReceiveProps that's currently marked unsafe. componentWillReceiveProps will update state synchronously and componentDidUpdate will update state asynchronously.

Steps to Reproduce

1. Go to anyOf field in storybook of the latest version of master
2. Add a new entry and keep it selected as option 1 and enter some text in the input field
3. Add another entry and select option 2 and enter some text in the input field
4. Move the option 2 up in the array.
   

Expected behavior

The array should have the two positions switched.

Actual behavior

The array only has one position switched correctly, while the other has the wrong selected option even though the state has been changed.

Version

v.1.8.0

Just confirming -- is the same issue is happening with the latest code on the master branch (https://rjsf-team.github.io/react-jsonschema-form/)? We added in a few changes that might have fixed it in #1352

[SuriGill]

Yes, when running the devserver playground of the latest version on the master branch with the changes from #1352, I still run into this problem.

I've also found another issue that is related to the anyOf schema incorrectly rendering. I was unsure if I should make another ticket or include it in this issue. The steps to reproduce:

1. Go to anyOf field in storybook of the latest version of master
2. Add two new entries in the items
3. Move item one down
4. Try typing in the second item
   

The expected behaviour is that the second item input should correctly update. However, the first item is updating and incorrectly at that as well.

This issue has to do with the schema not re-rendering after a change because the only prop that is changing is the idSchema which is not resolved in shouldComponentUpdate here:

Fixed by #1491 and #1493.
