No more use audio mime type for voicemail uris.

This makes the uri handling simpler, as we voicemail uris can now only
be of item or dir and does not depend on the content.

This also avoids strict mode violation when getType is called from UI
thread.

There is no change needed in the contacts app because the URI mime type
is right now used by the app.
