Fix compatibility of unit tests with react-hook-form 7.56.x

[slax57]

Problem

Upgrading react-hook-form to v7.56.x breaks some unit tests.

Failing test suites:

packages/ra-ui-materialui/src/input/ArrayInput/SimpleFormIterator.spec.tsx
packages/ra-ui-materialui/src/input/SelectArrayInput.spec.tsx
packages/ra-ui-materialui/src/input/NumberInput.spec.tsx
packages/ra-core/src/controller/input/useReferenceInputController.spec.tsx
packages/ra-ui-materialui/src/list/filter/FilterButton.spec.tsx (flaky)

Solutions

SimpleFormIterator

Regression brought by #9795, somehow unseen 🤷 🤔

SelectArrayInput

Same: not sure how we did not see that...
The code of the story used by the test was wrong... 🤔

NumberInput

This one is actually a RHF regression, I've opened an issue:

react-hook-form/react-hook-form#12815

useReferenceInputController

Render count needs to be increased from 3 to 4. Fixed by simply awaiting the expected call.

FilterButton

Flaky tests.
Fixed by adding timeouts.

How To Test

1. yarn up react-hook-form
2. make test-unit
3. All tests should pass, except NumberInput

Did you try to find a way to remove the ts-ignore?

no, this is out of scope for this PR IMO
