Restoring Group and Meters test has exposed similar issue as https://bugs.opendaylight.org/show_bug.cgi?id=2862, this is flow ID is unknown for a flow containing a group or a meter. Same as 2862, this was working in stable/helium.

Steps to reproduce:

1) start CPqD

2) Create a group:

PUT http://127.0.0.1:8181/restconf/config/opendaylight-inventory:nodes/node/openflow:1/group/1

group xmlns="urn:opendaylight:flow:inventory">
<group-id>1</group-id>
<buckets>
<bucket>
<bucket-id>1</bucket-id>
<weight>1</weight>
<action>
<order>1</order>
<output-action>
<output-node-connector>openflow:1:1</output-node-connector>
</output-action>
</action>
</bucket>
<bucket>
<bucket-id>2</bucket-id>
<weight>1</weight>
<action>
<order>1</order>
<output-action>
<output-node-connector>openflow:1:2</output-node-connector>
</output-action>
</action>
</bucket>
</buckets>
<group-type>group-select</group-type>
<barrier>false</barrier>
<group-name>Foo</group-name>
</group>

3) Create a flow with the group:

PUT http://127.0.0.1:8181/restconf/config/opendaylight-inventory:nodes/node/openflow:1/table/0/flow/1

<flow xmlns="urn:opendaylight:flow:inventory">
<strict>false</strict>
<hard-timeout>0</hard-timeout>
<idle-timeout>0</idle-timeout>
<instructions>
<instruction>
<order>0</order>
<apply-actions>
<action>
<group-action>
<group-id>1</group-id>
</group-action>
<order>1</order>
</action>
</apply-actions>
</instruction>
</instructions>
<table_id>0</table_id>
<id>1</id>
<match>
<ethernet-match>
<ethernet-type>
<type>2048</type>
</ethernet-type>
</ethernet-match>
<ipv4-destination>10.0.10.1/32</ipv4-destination>
</match>
<flow-name>forward</flow-name>
<priority>2</priority>
</flow>

3) Check operational:

GET http://127.0.0.1:8181/restconf/operational/opendaylight-inventory:nodes/node/openflow:1/table/0
