Don't use randomly generated IDs in actions

[marcfallows]

In our storybooks we use seedrandom to seed Math.random because we use them for visual regression. That means that the randomly generated IDs can result in duplicate keys:

Randomly generated id: https://github.com/storybooks/storybook/blob/master/addons/actions/src/preview.js#L16

Use of the ID in a key: https://github.com/storybooks/storybook/blob/master/addons/actions/src/components/ActionLogger/index.js#L22

And we all know how React feels about duplicated keys... 😞

Could a uuid be used instead?

@marcfallows Seems reasonable to me! Wanna make a quick PR?

Happy to raise a PR. Do you have a preference:

• Using node-uuid to generate a uuid
• Keeping it simple and have a runtime counter

Sorry for the delay, finally made a PR for this: #1347
