Responsively-app: Increase React components unit-test coverage with jest

@manojVivek Can we create a checklist of all the items we want to be covered so that different people can contribute small chunks? Something like this one: https://github.com/firefox-devtools/devtools-core/issues/415

@sidthesloth92 That is a good idea. But not sure if the checklist is the right way here, as testing each component is going to be a big chunk of work on its own.
But either way, I'll try to put together a list of components and add to this.

Definitely we can have separate issues. Since you have the in depth knowledge of the app you can create a complete list and then we can have a to-do list linking to individual issues and we can just check them out here.
