lost of contacts profiles when deleting non-related ring account
Issue generated from Tuleap's migration script. Originally submitted by: Guillaume Roguez (guillaume)
Lost all my contacts profiles (no more pictures, just single-colored circle) after deleting
a ring-account, non related to the one owning contacts.
\* the deleted account was a testing ring account, never used and w/o name registration.
\* ring.db seems to be valid with many embeeded images data
