removing check for already loaded orphaned, close #12446 (rebased onto develop)



This is the same as gh-2754 but rebased onto develop.

This should resolve issues with pagination in orphaned container. To test just click on the Orphaned Container and see if you can browse through pages back and forth. 

Note: you may wish to lower the value in setting.PAGE in case there is less then 200 orphaned images.
