[universal-redux] Global styles applied several times now

[0xsven]

After your latest bug fix (moving globalInjects to componentWillMount) global styles are applied several times on the server.

On your demo page (https://arc.diegohaz.com/) the global styles are applied 3 times. In my app which has a little more global styles, they are applied up to 12 times. It seems like this grows over time.

I will investigate a little and post my findings.

Maybe we need to move injectGlobal to outside the component. I'm not able to test this right now. Can you see if this works?

I just realised that it adds up with every page refresh

edit: what do you mean with outside of the component?

[diegohaz]

It makes sense. App is mounted on every page refresh. the *Mount methods aren't the right place forinjectGlobal indeed.

[diegohaz]

I mean something like this:

injectGlobal`
body {
margin: 0;
}
`

class App extends Component {
...

[0xsven]

That works!

Nice! Would you mind to send a PR with this on master (I merge with other branches later)?

The files are src/components/App.js and src-clean/components/App.js
