User story: When attempting to create a butler object with a stack newer than w_2017_43, I see the following error:    {code}  In [2]: repoN = Butler('/datasets/hsc/repo/rerun/private/nate/addFakesCoaddTest')  CameraMapper INFO: Loading exposure registry from /datasets/hsc/repo/registry.sqlite3  CameraMapper INFO: Loading calib registry from /datasets/hsc/repo/CALIB/calibRegistry.sqlite3  ---------------------------------------------------------------------------  AttributeError                            Traceback (most recent call last)  <ipython-input-2-7580970a312d> in <module>()  ----> 1 repoN = Butler('/datasets/hsc/repo/rerun/private/nate/addFakesCoaddTest')    /software/lsstsw/stack3_20171023/stack/miniconda3-4.3.21-10a4fa6/Linux64/daf_persistence/14.0-11-g0362164+2/python/lsst/daf/persistence/butler.py in __init__(self, root, mapper, inputs, outputs, **mapperArgs)      535         for repoData in reversed(repoDataList):      536             self._setParentRegistry(repoData)  --> 537             repoData.repo = Repository(repoData)      538       539     def _setParentRegistry(self, repoData):    /software/lsstsw/stack3_20171023/stack/miniconda3-4.3.21-10a4fa6/Linux64/daf_persistence/14.0-11-g0362164+2/python/lsst/daf/persistence/repository.py in __init__(self, repoData)      141             self._storage.putRepositoryCfg(repoData.cfg, repoData.cfgRoot)      142         self._mapperArgs = repoData.cfg.mapperArgs  # keep for reference in matchesArgs  --> 143         self._initMapper(repoData)      144       145     def _initMapper(self, repoData):    /software/lsstsw/stack3_20171023/stack/miniconda3-4.3.21-10a4fa6/Linux64/daf_persistence/14.0-11-g0362164+2/python/lsst/daf/persistence/repository.py in _initMapper(self, repoData)      170             mapper = mapper(parentRegistry=repoData.parentRegistry,      171                             repositoryCfg=repoData.cfg,  --> 172                             **mapperArgs)      173         self._mapper = mapper      174     /software/lsstsw/stack3_20171023/stack/miniconda3-4.3.21-10a4fa6/Linux64/obs_subaru/14.0-10-g69a8e8f2+2/python/lsst/obs/hsc/hscMapper.py in __init__(self, **kwargs)       36             calibSearch = [os.path.join(kwargs['root'], 'CALIB')]       37             if "repositoryCfg" in kwargs:  ---> 38                 calibSearch += [os.path.join(cfg.root, 'CALIB') for cfg in kwargs["repositoryCfg"].parents]       39                 calibSearch += [cfg.root for cfg in kwargs["repositoryCfg"].parents]       40             for calibRoot in calibSearch:    /software/lsstsw/stack3_20171023/stack/miniconda3-4.3.21-10a4fa6/Linux64/obs_subaru/14.0-10-g69a8e8f2+2/python/lsst/obs/hsc/hscMapper.py in <listcomp>(.0)       36             calibSearch = [os.path.join(kwargs['root'], 'CALIB')]       37             if "repositoryCfg" in kwargs:  ---> 38                 calibSearch += [os.path.join(cfg.root, 'CALIB') for cfg in kwargs["repositoryCfg"].parents]       39                 calibSearch += [cfg.root for cfg in kwargs["repositoryCfg"].parents]       40             for calibRoot in calibSearch:    AttributeError: 'str' object has no attribute 'root'  {code}    This seems to be related to DM-12117 but is not the same issue.    The changes that introduce the HSC failure come from [this commit|https://github.com/lsst/obs_subaru/commit/cc28b809c2cc0ca1ac7f81d43a69970ff8c6adb3].
