Flow is not getting installed for second DC-GW, when both the DC-GWs are in same vpn.

Steps to repro
====================
1)Do the basic configuration for all the CSS.
2)Form bgp neighborship between DC-GW1 and CSC.
3)Also form bgp neighborship between DC-GW2 and CSC.
4)Create mpls-over-gre tunnel for both.
5)Check the flows in the CSS, table21 should have an entry for both DC-GW1 and DC-GW2.

Description
=====================
When bgpvpn is updated via rest, karaf doesnt show it as updated however rest response shows it as updated.

Steps to repro
====================
1)Configure bgpvpn with multiple rds and verify the output in controller using "l3vpn-config-show -vid <vid>"
2)Update the rds and verify in the controller as in step 1.
3)Delete the vpn and reconfigure the same using rest call.
4)Verify the rest response and also in controller, works fine.
5)Now update the same using rest call and verify the rest response, it is properly updated.
6)Verify the same in controller,it throws error.

This issue is not reproducible.

But, an additional check if VPN targets are null:
