fix filter for the access_level INTERNAL

[kimakan]

The queues such as

    {
        'key': '5h',
        'label': '5 Hours',
        'timeout': 18000,
        'priority': 1,
        'access_level': 'INTERNAL',
        'groups': []
    },

were not filtered out for the not authenticated users. With the proposed fix, the filter works correctly.
