Missing ORIGIN attribute can break app-peer

In CSIT Userfeatures test job, "Ibgp Peer Lsp" suite sends update message without ORIGIN attribute (a current bug in the suite).

ODL disconnects the peer, but fails to perform correct cleanup.
There is a suite running before "Ibgp Peer Lsp" which configures and then deconfigures app-peer. "Ibgp Peer Lsp" suite itself does not interact with app-peer.

Every suite after "Ibgp Peer Lsp" fails at test cases which expect consequences initiated by app-peer (each time app-peer is configured anew). Test cases for bgp-rib consequences from external peer are still passing

Looking at karaf.log there seem to be a transaction chain left in failed state.
