Fix clear storage not working

It failed because it went looking for the focused / first window to
clear the storage on, but we called it before we had a window. Just
rewrite it without electron-clear-storage which doesn't really seem
necessary as a dependency, and also relaunched the app when clearing
stprage (you-had-one-job.gif). Pass the session in explicitly so it's
clear it needs it.
