Do not expose the NEW column in the Voicemail provider.

We added the IS_READ column, so that we can distinguish between items
that are new and items that have not been read (or heard, for
voicemail).

However, there is no reason to expose the NEW status of voicemail, since
that is about whether the user should be notified and it is handled
entirely by the content provider and Contacts application.

This is part of the changes needed to fix notifications for voicemails.
