Update fig vagrant

This fixes my issues getting the JRuby version of Panoptes running in Docker. Basically JBundler adds a `.jbundler` directory with classpath information. It's is specific to a host machine, so it needs to be deleted before the rails app is run so jbundler correclty recreates it. 
I'm not sure about this one. I think it's definitely right for cellect to fail fast and die when its database isn't there. 

Maybe supervisord's retry mechanism can be configured to allow increasing waits for retries? I haven't looked at its docs in a while so I'm not sure that's possible.
