Fix mutation hooks mutationMode option cannot be controlled

[djhi]

Problem

All our mutation hooks accepts a mutationMode option. However, if this option dynamically changes, the changes will be ignored. This is because we store the initial value in a useRef but never update it.

How To Test

• stories
• unit tests

Todo

• useCreate
• useDelete
• useDeleteMany
• useUpdate
• useUpdateMany

Additional Checks

• The PR targets master for a bugfix or a documentation fix, or next for a feature
• The PR includes unit tests (if not possible, describe why)
• The PR includes one or several stories (if not possible, describe why)
• The documentation is up to date

Also, please make sure to read the contributing guidelines.

Closing this as we already allow to pass different mutationMode and params at call time.
