Changing the theme doesn't work

[pomber]

Theme is not updated when I change the theme prop.
Minimal repro: https://codesandbox.io/s/9415mzmr0w

My current workaround is changing the key of the Highlight component together with the theme prop, so the component is mounted again when the theme changes (line 26 in the linked codesandbox).

Sorry I didn't have time to debug it today.

To be honest, this was pure laziness on my part 😆 It's an easy fix which I can do asap https://github.com/FormidableLabs/prism-react-renderer/blob/master/src/components/Highlight.js#L32-L34
