Pipeline flows are not consistently installed on OVS node with pre-existing integration bridge

On an OVS switch that has an existing integration bridge (e.g. br-int) before set-manager is called, the pipeline flows for that bridge may not always get installed on the switch once set-manager is called.

e.g.

[root@odl32 odl]# ovs-vsctl show
