Issue DM-6151: Failure to fail when fallbackFilterName is None
When no {{fallbackFilterName}} is set, we can get a confusing error message when failing to load a calib: {code} RuntimeError: Unable to retrieve dark for {'filter': 'U', 'date': '2016-05-12T02:58:56.591', 'ccd': 0, 'basename': '2016-05-12skyflats_02', 'object': 'FLAT', 'visit': 883, 'expTime': 20.0006, 'channel': 16} and no fallback filter specified: Unknown value type for filter: {code} This is unrelated to the calib load failure, and merely reflects the fact that {{fallbackFilterName=None}}.
