GTFS+ editor not showing multiple pages for a given table and missing route entities

[landonreed]

When viewing directions.txt for Tri Delta (Bay Area), only a single page of rows is rendering. There is also an issue where certain route entities are not rendering.

The multiple pages issue seems to be caused by not updating the state variable pageCount.

For missing route entities, there are a few issues. Errors not being caught when fetching routes. The main issue, however, is that the GTFS+ editor is fetching GTFS entities via the MTC two character feedId. This will fetch from the latest published version, not the version of GTFS+ data currently being edited. So if there are new routes or stops in the version being edited that are not found in the 'published' version, they will be missing. This should be fixed to fetch entities from the versionId (not two character MTC feed source ID).
