Per this graph we have a sharp drop in Nightly telemetry payload size:
http://ec2-50-112-66-71.us-west-2.compute.amazonaws.com:4352/#sandboxes/TelemetryChannelMetrics60DaysAggregator/outputs/TelemetryChannelMetrics60DaysAggregator.nightly.cbuf

Roberto found that we lost all histograms except TEST_RELEASE_OPTOUT and all keyed histograms except TELEMETRY_TEST_KEYED_RELEASE_OPTOUT.
From the above it looks like this is bug 1120369.

Apparently i didn't do the renaming of constants properly :(
DATASET_EXTENDED should now be DATASET_RELEASE_CHANNEL_OPTIN:
https://dxr.mozilla.org/mozilla-central/search?q=DATASET_EXTENDED&case=true
http://mxr.mozilla.org/mozilla-central/source/toolkit/components/telemetry/nsITelemetry.idl#38

It looks like we just end up only sending the _OPTOUT histograms because DATASET_EXTENDED is |undefined| and hence |0|.
It looks like we have not noticed this in tests because bug 1129504 accidentally removed test coverage in the last days :(

r+ if this is green on try.
I think this could use a better commit message though - we could just read the diff to see what exactly was replaced.

Looks good if this is green on try too.
Can we be a little more descriptive and mention the "missing telemetry payload test coverage" in the commit message instead of just naming the function?
