This makes the browser_UsageTelemetry_urlbar*.js tests pass for the all of the
FX_URLBAR_SELECTED_RESULT_* histograms apart from the "METHOD" one which will be handled
in bug 1500476.
I have handled the recording of telemetry in the controller, as this seems a better
location than BrowserUsageTelemetry.jsm due to needing to reach into the results and obtain
specific details.
