Correct i18next errors

[mcallisto]

The current demo was not fully working, throwing the following console errors:

• react-i18next:: Trans: the passed in value is invalid - seems you passed in a variable like {number} - please pass in variables for interpolation as full objects like {{number}}. 12 react-i18n-opt-bundle.js:30:14750
• i18next::translator: missingKey de translations <1>xxx</1> <1>xxx</1>

Now it is correct, even if I have not been able to trace the original demo, if there was one, so I am not totally sure about what was the intended result.

I went back to status Draft.

I wanted to make it more meaningful, but I am struggling to get Plurals, Context and Interpolation working...

This may lead to subtle reconciliation issues. Try rendering into a container element created for your app. react-dom.development.js:88:30

Cool, thanks!

Merge when you're happy with it :)

Thank you! Merging now, it is a small step forward anyway.

I will try opening an issue for remaining unsolved use cases.
