Write tests for marketplace management view - marketplace_management.feature

The view is located at http://drupal.org/drupal-services/manage.
Appropriate file would be marketplace_management.feature

Tests need to check that page exists and (at least some) filters on top of it work.

Proposed feature:
Feature: Marketplace Management
In order to manage marketplace listings
As an authenticated user
I should be able to search and filter the list of organization pages
