Observed behavior

In the GTFS editor, setting the continuous pickup/dropoff type for a route to a value of 2 and 3, respectively,
results in the route not being exported in editor snapshots.

2. Go to the route editor and select a route
3. Change the continuous pickup setting to 2, continuous drop off setting to 3.
4. Take an editor snapshot.
5. Download the snapshot ZIP
6. In the downloaded ZIP file, open routes.txt
7. Observe that the route changed above is missing from routes.txt.
