`QueryData` stores last used options to help decide when it should re-run. If new options (when compared against the previously stored last options) are found, `QueryData` will make sure the new options are passed into Apollo Client for processing. When `onCompleted` and/or `onError` options are set however, `QueryData` thinks the options received on each render are new as these callback functions don't have a stable identity. This can then lead to infinite re-renders. This commit adjusts the `QueryData` option equality check to ignore option callbacks. During normal use of `useQuery` it should be okay to ignore callbacks like this, as they don't normally change between renders. Fixes #6301
