Routes from BGP application peer not populated to example-ipv4-topology in case of zero routes initial POST request

In case of initial POST request without any route included, no consequent example-app-rib change is populated to example-ipv4-topology

distribution-karaf-0.3.3-SNAPSHOT

STEP 1/ python bgp_app_peer.py --command post --count 1 --prefix 1.1.1.1 --prefixlen 32 --de (initial POST request with one route introduced)
STEP 2/ python bgp_app_peer.py --command add --count 1 --prefix 1.1.1.2 --prefixlen 32 --info (consequent POST single route request)

result: SUCESS

STEP 3/ python bgp_app_peer.py --command post --count 0 --prefix 1.1.1.1 --prefixlen 32 --de (initial POST request without any route introduced)
STEP 4/ python bgp_app_peer.py --command add --count 2 --prefix 1.1.1.1 --prefixlen 32 --info (consequent two POST single route request)

result: FAILURE
