Prefer the callbacks passed to the execute function returned from useMutation

[jerelmiller]

Closes #10287

Prefer calling the onError and onCompleted functions passed to the execute function returned by the useMutation. Currently both the callbacks passed to the execute function and the callbacks passed to the hook itself are called. According to our docs, this should not happen as the options passed to the execute function should override the hook options.
