update react-automata

[kriswep]

This tackles #82 .
Updated the react-automata version, as well as react, react-dom and react-scripts.
The update to react-automata required some API changes, which were done in index.js. It also required react-test-renderer as a dependency. See react-automata #32 for a discussion.

Also, as asked in #82 I don't know what you mean by out of date, including the tests. Can you elaborate on that?

Awesome work @kriswep - any way you could also update the React Native version?

[kriswep]

Oh, I see, you were refering to the RN version with the test. Totally missed that.

Afraid I don't have a plain RN environment set up.
Would you be on board with converting to expo/create-react-native-app? I could work on that. If yes, should that happen in here, or in a new PR?

[GantMan]

No worries!

Since there's an existing react native app without expo, I'd like to keep it how it is. If you can file a ticket for a new issue saying "Update react-automata for React native" link to this, I think we can merge and close this one knowing there is a placeholder.

[kriswep]

Please wait with merging. Just noticed an error with the clear transition after the upgrade. Will investigate.

[kriswep]

Alright, should work now.
I had to basically force the transition actions on the CLEAR event to happen, without an actual transition.
That's why there is a cond on the CLEAR events and a value on the transition.

Also the issue regarding RN update was added, #88

Thanks so much @kriswep - welcome to the contributors!
