Fixing double-rendering of USD prims + autotest

Nice catch! @vlasovi, I assume now, we can get similar fps on USD scene as corresponding Maya scene , right?

Yes

Looks good to me, though I wouldn't tie the test to the scene browser.

Thanks for the test, looks good, but it feels out of place to tie it to the scene browser. I asked @debloip-adsk and he agreed with me, saying that

with APIs like GetChildPrimPaths, GetPrim, Get methods for container data sources (or GetElement for vector data sources) + casts, and GetValue/GetTypeValue methods on data sources, the whole scene index scene hierarchy can be inspected.

Here's an example you might like:

It shouldn't change the logic of the test.

Great work, thanks for the test!
