Disco#info barejid instead of domain only on carbons

There is no apparent reason why a disco#info should be done on the
domain Jid rather than the bare Jid. MUCs advertize their MUC-y-ness on
the bare Jid. This will also fix cases like chat@dino.im which is a MUC
component itself (whereas dino.im is a user host), and biboumi
components that serves a mic of MUCs and (IRC) users.
