esf template fails

[jezmartin]

First issue is a dependency for Log4js missing from the package.json.
Second issue appears when add-on is correctly deployed and configured in the add-on console. When then setting up a place to use the external storage Jive pops up a red error banner and the node.js server console reports Error: No Community found by the TenantId: http://localhost:8080

I was running a local Jive developer instance so the community reported was localhost:8080
