Add quizzes caching for tabs

[krambertech]

Now every time I change tab all quizzes are reloaded. They could be easily cached

@krambertech For loading default data, you could load it on server side, i.e. create function to fetch default data before/after fetching components data. To keep it isomorphic, you could also dispatch from the App lifecycle event componentDidMount for fetching the default data on the client side.

In this particular case, I guess loading quizzes per tab change is the wanted behavior: different quizzes for each tab.
