Blank output when at least one resource has restricted access

[pitangaweb]

1. Create 2 resources and publish them on the same month, under the same parent.
2. Restrict access to one of these resources by putting it into a "member" resource group.

Create a resource and embed the Archivist snippet. Logged in "members" will see the snippet output, logged out visitors will see nothing whereas one of the 2 resources is accessible to everybody.

I was able to fix this by editing the snippet source code, replacing getIterator (line 136) with getCollection. But I'm not sure if it's the correct way to do it.
