[Building Sakai] Samigo NPE on group assessment

[Paul Lukasewych]

Something like this can happen when a group is deleted and therefore the test 
has no valid groups assigned to it. Usually the remedy is to switch the test 
to be released to the whole site, with something like this:

UPDATE sam_publishedaccesscontrol_t SET releaseto = '##site name##' WHERE 
assessmentid = ##publishedassessment_id##
