Fix errorPolicy on useMutation hook

[jamesreggio]

Hello Apollo folks 👋

The useMutation hook exposes errorPolicy in its option typings, but doesn't pass the value through to the underlying mutate method on the ApolloClient instance.

This seems like an oversight, since there's value in being able to specify errorPolicy: 'all' and have the hook's mutate function resolve (not reject) with an error field.

I've fixed this minor bug and wrote some tests to prevent future regressions.

This fix relates to this issue from the deprecated react-apollo repo: apollographql/react-apollo#3728

Hey @hwillson, don't mean to be a pain, but do you mind taking a look at this? Multiple people are encountering this issue.

Sorry for the delay here @jamesreggio - this looks great! Thanks!

[Zigonja]

Thanks! This was a much needed fix for my case

@jamesreggio @hwillson does the recent merge here mean that updating apollo-client package will include the fix, or do we need to wait for a release?

@t-lock These changes are now available in @apollo/client@latest.
