This happens if you type fast enough to beat the component updater downloading the tor component. The tor component updater initializes the tor executable path only after the component is downloaded, but the only place that we choose to launch tor is when we construct the TorProfileServiceImpl -- which may happen before the tor component has been downloaded.

Resolution: Maybe we can teach BraveTorClientUpdater::OnComponentReady to notify the TorProfileServiceImpl that it can launch tor now.

Probably fixed by brave/brave-core#7069

Added it to 1.19.x milestone so it can be retested.
