filter tdil collections

I'm not sure how you guys aren't having this problem on your development environments, I know in production PersonalCollection and CourseCollection objects aren't in MIRA but on development I'm sharing a Fedora/SOLR instance and I thought you guys were doing the same.  I'm happy to add a test for this if it makes sense to merge this, I'm just not sure where since I can't template PersonalCollection/CourseCollection in mira.
