This is part of the requested refactor for hacktoberfest mentioned in #2621.
@Saeris @christianalfoni

What is the current behavior?

Previously it was utilizing inject and hooksObserver from app/componentConnectors.

What is the new behavior?

Uses useOvermind and useEffect to access state and perform checks on isLoggedIn.

What steps did you take to test this? This is required before we can merge.

1. yarn lint
2. yarn test
3. Ran locally, but not sure where this is used.

Heyo! Thanks for the contribution! This can be tested by trying to fork codesandbox.io/s/node (so in localhost) and seeing if the modal pops up and it closes + forks when you sign in.

@alanhoskins Awesome work here! We just found a tiny thing related to importing the component. No wonder, it has not been refactored to Typescript yet :)

Please merge in this PR: https://github.com/alanhoskins/codesandbox-client/pull/1

And we are ready to ship this!
