Fix lint errors

Manually fix all lint errors.
Some errors could not be fixed, a TODO comment was added.

To fix errors caused by `react-hooks/exhaustive-deps`, missing
dependencies were added to the dependencies array of some `useEffect`
calls.
We need to make sure that all `useEffect` call work as intended before
merging
