Visualization "Unable to retrieve..." errors shouldn't dump a whole stacktrace

Visualization can have various issues if the user doesn't have permission to see certain attributes. These don't need a whole stacktrace for that, as it's obviously either permissions or a missing attribute.

• "Unable to retrieve attribute " + loaderMetadataGroupIdName + "; results will not include groups loaded by jobs"
• "Unable to retrieve PSPNG provision_to attribute; results will not include provisioning relationships"
• "Unable to retrieve attribute for sql loader jobs; groups might not be detected as loader jobs"
• "Unable to retrieve attribute for Grouper object types"
