Saving ALL state when contact editor is evicted

We failed to save three of the fields in onSaveInstanceState
As a result we would be
1) unable to attach a photo to a contact
2) get an out-of-memory situation if a sync is running at the same time
3) not be able to join a contact manually if the process is interrupted
