   I'm a little wary of this change. Currently, there's ambiguity as to what we 
should do if a transform and its surrounding composite both declare a 
(non-trivial) type constraint on an output PCollection. Previously, the inner 
transform would win, but this changes it to let the outer transform win. 
   
   That might fix this test, but might break others. 
   
   One option is to actually address the TODO here and implement (best-effort?) 
intersection.
