React branch update with hooks - New react/typescript branch? about todos

[filipenevola]

Hi @cvolant sure, please open your PR and let's do it.

I now have a working branch that updates everything, transforms all class components into functional components, creates a simple hook-handled global state, fixes some issues (menu, not-found), improve PropTypes, BUT... breaks tests. :(

I searched for a solution a whole day without success: I am tired of it, and I have others things to do. Testing in Meteor already wasn't very documented long ago, and there isn't any other new documentation since then, so now it is both scarce and outdated... It would be great to be able to use react-testing-library...

Do you think I should submit the PR and then we try to fix the problem, or we first need to fix the problem?
If anyone wants to try, here it is:

@cvolant please submit the PR then we can work together in the testing part. Sound good?

@filipenevola OK then here it is: #277
If you can have a look at the tests, that would be great. I tried mounting, shallowing, rendering the ListHeader, but no luck, I keep running into errors no matter what I try with each of them...

I improved the PR thanks to HorusGoul review. The tests are still broken, but it is better.
The server tests all pass, but 3 of the client tests fail, I don't know why...
