Title: Fixing missing marketProjection filter when calling listMarketCatalogue ...

The Java code sample's API doesn't use the marketProjection parameter in the request for listMarketCatalogue() , so no Runners, Descriptions, etc.. was returned from the gateway for the "rescript" or JSON requests.

These 3 lines fix the issue.
