[Firefox] Ensure that telemetry will be correctly recorded even when the PDF header is missing (bug 1606566)

Browse Source 
As suggested in the bug we'll now always fallback to "other", which should be fine considering that that value is listed in the histogram definition; see https://searchfox.org/mozilla-central/rev/331f0c3b25089c9a16be65f4dc8c601aeaac8cc4/toolkit/components/telemetry/Histograms.json#9097-9106
