fix(gui-client): remove bad hook dependencies (#9537)

The removed hook dependencies are invalid because the side-effect
specified in `useEffect` does in fact not depend on them. However, as a
result of these dependencies, the `useEffect` closure appears to run in
an end-less loop, constantly sending the `update_state` command to the
backend which in turn re-sends all state to the frontend, causing a
massive CPU and memory spike.

Resolves: #9519
