Bug 1424760 (Part 7) - Don't insert an extra property into the GC telemetry r=Dexter
The properties limit was being exceeded because the telemetry code itself added a num_slices property. The GC already adds a slices property (containing the number of slices) so I've fixed the issue by removing the creation of the num_slices property, which will stop this limit from being exceeded. --HG-- extra : rebase_source : dd5c54fe88f4511b4dffa6e52b7b4d8709886f42
