add reset method to useMutation

[vankhoawin]

This PR adds a reset method to the useMutation's MutationResult. This function would be useful in cases where a React function's state should be reset to how it was originally, at initialization. As far as I know, there is only one way to update the data within a useMutation call: https://github.com/tannerlinsley/react-query/blob/07b0a66f39a9ce3b5b61ec720f3aebae6128bce2/src/index.js#L639

This PR also adds a test and some setup for more testing using react-testing-library.

And great work on the project, really been liking the API so far!

PS I'll add TS typing if this PR is approved.
