Point Instancer Transform collapses when referenced under Instanceable Prim

[caammann]

Description of Issue

Transforms on PointInstancer prims get discarded when nested under a prim which gets referenced as Instanceable.
Possibly related to #1622

Steps to Reproduce

1. Load the following example in usdview: nestedPointInstancerTransform.zip
2. The "instancer1" PointInstance prim includes a translation in y.
3. That translation persist when referenced "non-instanceable" (/nonInstanceable prim), but gets lost when referenced "instanceable" (/Instanceable prim)
