Fix duplicate "nactive_huge" JSON key in HPA shard stats output

Browse source 
In both the full_slabs and empty_slabs JSON sections of HPA shard
stats, "nactive_huge" was emitted twice instead of emitting
"ndirty_huge" as the second entry. This caused ndirty_huge to be
missing from the JSON output entirely.

Add a unit test that verifies both sections contain "ndirty_huge".
