Fix frontend console warnings

[tomatocat]

Describe the bug
When running from the local development server, the console warns about some bugs like depreciated methods and not having ComponentWillUnmount in Canvas.js. This may cause memory leaks or future issues.

Screenshots
maybe add later

I figured out that the recompose library is one cause for the createFactory() warning. I checked their Git repo and it looks like there's already an issue about it, so there's not much we can do about that library.
