Storybook: "Stateless function components cannot be given refs" warnings with React@next

[ConneXNL]

I am using the react@next branch with the initial fiber support.

Upon loading the storybook I get 2 warnings:

Warning: Stateless function components cannot be given refs. Attempts to access this ref will fail.

Check the render method of `Container(LeftPanel)`.
    in LeftPanel (created by Container(LeftPanel))
    in Container(LeftPanel) (created by Layout)

and 

Check the render method of `Container(ShortcutsHelp)`.
    in ShortcutsHelp (created by Container(ShortcutsHelp))
    in Container(ShortcutsHelp)

Things seem to work normally though.

Anyone who wants to pick this one?

I feel it should be an easy one to get started contributing to storybook, so send me a message if you want to give this a go and want my help!

@ndelangen I think I'll try to pick this

Ok, so #1551 fixes the symptoms, but the origin of the problem is react-komposer adding refs to children just for tests. I will send them a PR, but unfortunately the repo looks abandoned, so we should probably switch to recompose.

[ndelangen]

@Hypnosphi That sounds like the best course of action indeed! Will switching to recompose be easy you think?

[Hypnosphi]

Well, I haven't really digged into it, we should check that it provides the needed features. It may turn out that transferring react-komposer will be a better option (if that's OK for @arunoda)

if somebody is going to connect with @arunoda please ask about https://github.com/arunoda/podda as well!

[Hypnosphi]

@ndelangen we can achieve the current behaviour using recompose's mapPropsStream and some lite-weight observable stream library (I'd suggest xstream).

React 16 should be fully supported now. Closing.

This issue is not about React 16 support

@ndelangen fixes this as part of #3628
