Alembic procedural: fix missing update when only the transforms change

The missing update has two sources:

The TimeSampling used for looking up transformations in the cache was
uninitialized. To fix this, simply use the TimeSampling from the last
transformation in the hierarchy (that is the object's parent), which
should also contain the time information for all of its parents.

The objects are not tagged for update when their trasformations change.
