pipeline flows are not installed correctly if OVS has manager set before netvirt feature is installed

SETUP:

ovs_version: "2.6.1"
ODL snapshot: distribution-karaf-0.6.2-20170803.213544-260
features installed: odl-netvirt-openstack

STEPS to reproduce:

1. start with a clean OVS

2. set-manager of OVS to point to fresh ODL
014bd065-2822-4ab4-bfc5-4327a5646a81
Manager "tcp:192.168.254.33:6640"
ovs_version: "2.6.1"

3. start the fresh ODL and install netvirt

4. ODL automatically creates br-int and sets br-int's controller to point to ODL but the pipeline flows appear incorrect; there are missing flows (a table=213 flow and a table=243 flow are missing), and most of the flows appear to have an incorrect "actions=drop" configuration.
