set state filter for offline job queries

* Respond to schema changes in cylc/cylc-uiserver#657
* Jobs queries used to only return succeeded jobs (all the analysis
  view cares about).
* The `states` and `exstates` filters have now been implemented to allow
  jobs in other states to be queried (to support new views).
