flow details not present in flow-node-inventory

This bug is to track failures in CI.

https://jenkins.opendaylight.org/releng/view/openflowplugin/job/openflowplugin-csit-1node-cds-flow-services-all-master/

after programing a flow, and while it exists on the switch, it is not seen in the output to from:
/restconf/operational/opendaylight-inventory:nodes/node/openflow:1/table/0

the output is this:

{"flow-node-inventory:table":[{"id":0,"opendaylight-flow-table-statistics:flow-table-statistics":{"packets-looked-up":976444,"packets-matched":976408,"active-flows":10}}]}

the output used to have a format like this:

{"flow-node-inventory:table":[{"id":0,"opendaylight-flow-table-statistics:flow-table-statistics":

{"packets-looked-up":976209,"active-flows":10,"packets-matched":976149}
