Default account backend: when deleting, always delete from both places

Our tracking of whether something is "secret" (in the gnome-keyring) is
pretty shaky, and in particular, we can forget that things are meant
to be "secret" sometimes (we lose that information when deleting
parameters).

Happily, when we're deleting things, it doesn't actually matter: the
right thing to do is clearly to delete from both locations, regardless
of where we think it ought to be.

Similarly, when we're setting a property to a new value, it's appropriate
to delete it from both locations, then put it in the right location
(only).
