flows -j breaks after adding point intents (update REST codec)

commit c17042d9e53814935b4c85ad304543e99b36f10d

Refactor: Rename the class and method to make them more descriptive

• Rename from FlowModBuilderHelper to OpenFlowValueMapper
• Rename from UnsupportedConversionException to NoMappingFoundException
• For methods, use "lookup" instead of "convert"

After installing point intents I check for flows state using flows -j command but I kept getting error executing the command:

onos> flows -j
Error executing command: org.onosproject.net.flow.criteria.OchSignalTypeCriterion cannot be cast to org.onosproject.net.flow.criteria.OpticalSignalTypeCriterion

Here is the log:
