Ignore/clear default access for all unlicensed apps

The JIRA invite plugin currently decides if an invite is acceptable based of the instances 'Default Application' settings. For example, at some point in time an instance had a license for JIRA and Confluence. This instance's default application settings were JIRA and Confluence. The license is updated to a JIRA only license. Invites fail due to not enough available licenses since Confluence is still a default application.
