Scope down lastTransferTime to only ContactResource, DomainResource

and HostResource.

DomainApplication is not transferable and has no need for this
field. HostResource needs it because it can be transferred with
a domain.

This is all in service of removing the ofy().load() inside of
host's cloneProjectedAtTime.
