Merge pull request from minrk/no_engines...

Merge pull request from minrk/no_engines Improve Hub/Scheduler when no engines are registered 1. Tasks are pulled into the schedule, rather than left on the ZMQ queue, which means they enter the database. 2. queue_status will not raise NoEngines when there aren't any, instead it will still fetch the available information. Bug fixed in db_query, where behavior did not match docstring (buffers should be excluded if no keys are specified). closes (again)
