Fix useMutationWithMutationMode in optimistic and undoable mode may pass invalid parameters to the mutation

[djhi]

Problem

After #10857, when passing parameters at declaration time to a mutation hook in optimistic or undoable mode, those params may be modified by the side effects before the actual mutation is called.

For instance, if you pass the selectedIds from the ListContext to a useUpdateMany hook and use the useUnselectAll hook to reset the selectedIds in the onSuccess side effect, then the actual mutation will be called with an empty array of ids.

You can see the issue like this:

• https://stackblitz.com/github/marmelab/react-admin/tree/master/examples/simple
• select multiple rows and click the Reset views button
• check the dataProvider call in the console and check the call to updateMany
• beside, the views are back to their initial values once the mutation is actually called

Solution

Keep the params in an additional ref that is freezed once the mutate callback is called.

How To Test

• make run
• http://localhost:8080/#/posts
• select multiple rows and click the Reset views button
• check the dataProvider call in the console and ensure the correct ids were passed to updateMany
