Support external cross-project dependencies in ui

When a cross project dependency includes a change from a project
that is not known to zuul, the zuul ui stops updating and the following
stack trace is seen in the zuul logs on every ui update.

2015-06-12 12:42:50,079 ERROR zuul.WebApp: Exception formatting status:

AttributeError: 'NoneType' object has no attribute 'name'

Quick fix to stop the bleeding is to mark the project as "unknown".
An alternative is to simply leave it blank.
A more permanent fix is still needed (e.g. look up name of project).
