fix bug in stale profile clean up for clusters...

fix bug in stale profile clean up for clusters "clusters" tab of my notebook wasn't rendering, so checked the log, found the stack trace: ``` [...] File "/usr/local/lib/python3.4/site-packages/ipython-3.0.0-py3.4.egg/IPython/html/services/clusters/handlers.py", line 21, in get self.finish(json.dumps(self.cluster_manager.list_profiles())) File "/usr/local/lib/python3.4/site-packages/ipython-3.0.0-py3.4.egg/IPython/html/services/clusters/clustermanager.py", line 77, in list_profiles self.update_profiles() File "/usr/local/lib/python3.4/site-packages/ipython-3.0.0-py3.4.egg/IPython/html/services/clusters/clustermanager.py", line 74, in update_profiles self.profiles.pop(stale) TypeError: unhashable type: 'set' ``` looks like a pretty straightforward mistake
