Adding a flow using the Forwarding Rule Manager and the New OF1.3 Plugin causes an NPE

To reproduce,

1. Run the controller distribution from the openflowplugin project
2. Populate topology with mininet
3. Add flow using the following format,

PUT http://localhost:8080/controller/nb/v2/flowprogrammer/default/node/MD_SAL/openflow:1/staticFlow/flow1

Headers:
Content-Type: application/xml
Accept: application/json

Body:

<flowConfig>
<installInHw>true</installInHw>
<name>flow1</name>
<node>
<id>openflow:1</id>
<type>MD_SAL</type>
</node>
<ingressPort>openflow:1:3</ingressPort>
<priority>500</priority>
<etherType>0x800</etherType>
<nwSrc>9.9.1.1</nwSrc>
<actions>OUTPUT=openflow:1:3</actions>
</flowConfig>
