Thread cache always empty in SdfPath::AppendChild?

Hi there,

I was looking at SdfPath::AppendChild today and noticed that while it makes a lookup into the per-thread cache, it doesn’t seem to ever call Store() for it.

The situation seems different with AppendProperty where Store is effectively called toward the end of the method. I might be mistaken but just wanted to raise that observation.

Thanks Mark, good catch! It looks like this was inadvertently removed in a previous change. I have fix that restores it. Cheers!
