Migrate contact_email and contact_phone to allow dupes

The key item here is that comms.phone and comms.email are meant to
represent a real global namespace, but comms.contact is meant to
represent an organization-specific namespace. This means the mapping,
comms.contact_phone and comms.contact_email can't key off the global
namespace. Otherwise the contact namespace would implicitly be global.
