I found two articles (with contradictory information) :
Understanding Third-Party Next-Hop
RIP’s third-party next-hop behavior is fully automatic. You cannot disable or enable it
DMVPN Phases in distance vector
RIP

At first I thought that in RIP, you can’t turn of third party next hop, meaning that RIP shouldn’t work in Phase 1 and 3. Turns out I was wrong. First off, you can turn it off by running RIP version 1. But, even with third party next hop, you can send a packet through the tunnel with another spokes tunnel IP as destination, and the Hub will happily forward it. So long as you turn off split horizon on the hub, you are fine:
      
Phase1-1(config-if)#interface tunnel 1
Phase1-1(config-if)# no ip split-horizon
Generally, it is either automatic, or turning off split horizon will/can influence that RIP does not change IP address to itself (Otherwise RIP will put advertising router (itself) as next-hop). Looks like there is no way to manipulate RIP next-hop filed inside RIP advertisement (at least not in Cisco and could not find it for Juniper either).
