System prop to keep stale account data

If set to 1 (adb shell setprop debug.contacts.ksad 1) the provider
won't remvoe any data when accounts are removed.

This should be used sparingly; even though there are data still available,
the UI don't know anything about them, so they won't show up in the contact
filter screen, and the contact card/editor may get confused to see unknown
custom mimetypes.
