Editor: GraphQL request for calendars omits records if count is greater than 50

[landonreed]

Observed behavior (please include a screenshot if possible)

When loading a GTFS feed with lots of calendars (> 50) into the editor, viewing the list of calendars in the editor will omit calendars from the list.

Expected behavior

Full list of calendars should be visible. The datatools-ui GraphQL query should request a list without limit (limit: -1).

Steps to reproduce the problem

1. Import Dutchess_GTFS.zip into Data Tools and open in Editor.
2. View calendars and observe that calendar with service_id 38 is not in list (a number of others are missing too).

Any special notes on configuration used
