1. registered dummy21
2. registered dummy23
3. Added dummy21 via DimeUserResolver to contact list of dummy23
4. Tried to share a livepost via the "New livepost dialog" to dummy21
5. dummy23 not added to contact list of dummy21
6. livepost not in list of dummy21
7. no user notification received at dummy 21

Also sharing to an user registered at the Fraunhofer server is not working.
