Add server-side controller with client registry

See merge request !39

The server controller now check that there is no client registered for the given
room before creating one.

Since it handles client creation, the controller now manager the registry.

Add corresponding tests.

The (currently very basic) client creation logic is now into a
dedicated (actual) `controller` module.

This will allow for cleaner dev and (especially) tests.

Server-side module `controller` used a confusing name not actually reflecting
its purpose. Rename it to the more accurate `loader` name.

This will allows to easily create multiple clients later.

First step to handle multiple, non-conflicting clients connecting to different
rooms.

`xo` was the only package not to be fixed to an exact version. Fix (hoho) this.

yarn.lock update was long overdue. Some old dependencies were not removed.
