lrc: do not assume ip2ip account exits
Issue generated from Tuleap's migration script. Originally submitted by: Guillaume Roguez (guillaume)
The daemon has been updated to no longer require nor create an ip2ip account by default; this change has not been reflected in lrc which still assumes its existence.
This bug was originally discovered via the following crash in Ring GNOME:
On gnome client, typing "toto" (not existing contact) raising a segmentation fault.
