When going to about:telemetry, then selecting a section for which no histograms are available, it will break (or after bug 1302681 fall back to the parent ones).

https://dxr.mozilla.org/mozilla-central/rev/7d2e89fb92331d7e4296391213c1e63db628e046/toolkit/content/aboutTelemetry.js#2085

This needs some cleanup:
- the section "hasData" when *any* of `payload.parent.histograms` or `payload.processes.<P>.histograms` exist and are non-empty
- this should not fall back to the parent histograms
- for empty processes this should either 1) disable the process entry or 2) just show empty tables
The same goes for the keyed histograms section.

Does this mean i should drop the "part 2" patch in bug 1302681?

Yup, I think it will probably only causes merge conflicts :S
