Fix the rest of the places in the notifier that have buggy return values.

I don't believe these methods actually return the buggy
return values, because it seems unlikely they'd get called when
their conditionals would fail. (And they have to fail the conditionals
in order to return the "wrong" values)

For example, it seems unlikely that restart_activedirectory would be called
if the directory services were set to !activedirectory, which is what
would have to happen to get bogus return values.
