Show Calendar - Add host filtering to series/update endpoint

## Description of Issue
If a user is on the calendar and filtering by host, if they make changes to the series the endpoint will return shows that they are not currently a host on.

To fix this:
- [ ] Frontend - Get the latest filtering applied to the calendar from state
- [ ] Frontend - Add the filtering to the current action
- [ ] Backend - in the shows/find controller export functions that handle the various filtering scenarios
- [ ] Backend - Import functions into the shows/find and shows/series/update files so they both will return filtered data.
