Extra path-id argument on fluorine l3vpn

In userfeatures this test 010_Bgp_Functional_L3Vpn fails due to additional argument in output.

It's in effective-rib-in and loc-rib but not in adj-rib-in on FLUORINE
on O2 it's not present at all

 "label-value": 24005 } ],
+ "path-id": 0,
"prefix": "1.1.1.0/24",
"route-distinguisher": "1.2.3.4:1",
"route-key": "WAABAQIDBAABAQEB"

Steps to reproduce
1)Run bin/karaf (fluorine)
2)Install>
feature:install odl-restconf
feature:install odl-bgpcep-bgp
feature:install odl-bgpcep-bgp-config-example
3)run

./reconf.py

4)run exabgp with

env exabgp.tcp.port=1790 exabgp --debug exabgpl3vpn.cfg

5)check full rib output with

curl -H "Accept: application/json" -u admin:admin "http://localhost:8181/restconf/operational/bgp-rib:bgp-rib/rib/example-bgp-rib"

See the

"path-id"

extra argument

It is not present in oxygen, therefore the current test verification fails.

Let me know if it is there to stay, so I can adjust data.json against which it is compared.
