 Steps to reproduce:

 1. Start master.
 2. Open Web UI.
 3. Restart master.

 Try to check in web UI different lists, e.g. list of builders, last
 changes, workers.

 Expected behavior: browser should reconnect and display proper results. At
 least display that there are errors.

 Observed behavior: web UI silently display empty results, i.e. no
 builders, zero changes, no workers.
