react-admin: Editing a record throws Total from response is not a number error

What you were expecting:

Expect it won’t log any error in console when changing filter on a ReferenceManyField What happened instead:

Total from response is not a number error is shown in console when filter prop is changed on ReferenceManyField Steps to reproduce:

1. Go to codesandbox https://codesandbox.io/s/elastic-surf-urpjz
2. Edit a post -> go to comments tab
3. I added a body filter to filter comments in the comments tab in PostEdit.js. Change the body filter by typing some characters
4. Total from response is not a number. Please check your dataProvider or the API error is thrown in console

Other information:

This is the line which throws the error https://github.com/marmelab/react-admin/blob/master/packages/ra-core/src/dataProvider/useQueryWithStore.ts#L121.

I wonder if the check here https://github.com/marmelab/react-admin/blob/master/packages/ra-core/src/dataProvider/useQueryWithStore.ts#L119-L120 is suitable for useGetManyReference / ReferenceManyField.

When the filter prop is changed, useGetManyReference will use a new relatedTo to select ids & total from store, but we are comparing them against the old relatedTo (generated using old filter prop)'s ids & total.
