Saving already switched the language everywhere strings are made at the
moment they are shown: the tray is rebuilt, the indicator and the message
box translate as they speak. The settings window is the one place written
once, at construction, so the window that took the new language was the
one place still showing the old one, and a tooltip asked for a restart.
Now the window remembers the language it was built in, and a save that
changed it has the app replace the window: a fresh one comes up where the
old one stood, on the same tab. The restart tooltip goes, having nothing
left to excuse.
