localhost:8080 needs trailing slash

[caver456]

with CTP 2.0.0, noticed by Steve, duplicated on the dev machine:

211237 [caltopo_python:270:INFO] Opening a CaltopoSession object with no associated map.  Use .openMap(<mapID>) later to associate a map with this session.

211237 [caltopo_python:1244:ERROR] Sync returned invalid or no response; sync attempt failed.  Response: False

Workaround is to include a trailing slash in domainAndPort. Need to determine why it's needed for localhost:8080 but not needed for caltopo.com.
