Clarify "Save on Exit" tooltip

The old text, "Save modified preferences on exit" suggests that only the
modified preferences are saved. This is not the case: all preferences
are saved at once. This distinction is especially important after having
loaded factory default settings.

As discussed with @campbellbarton and @JulienKaspar.
