 When I start a new build, the 'Build Properties' tab does not get filled
 until I reload the page.

 There is an error message in the web console: Failed to load resource: the
 server responded with a status of 404 (Not Found)

 The URL is: http://local-buildbot:8010/api/v2/builders/9/builds/9

 When I access the url manually I get :
 "{"error": "not found while getting from endpoint for \n
 /builds/n:buildid\n        /builders/n:builderid/builds/n:number\n
 with arguments ResultSpec(**{'fields': None, 'limit': None, 'order': None,
 'filters': [], 'offset': None}) and {'number': 9, 'builderid': 9}"}"

 When I visit http://local-buildbot:8010/api/v2/builders/9/builds I can see
 a total of 8 builds.
