The tests in test_projection_expression.py test that ProjectionExpression
works - including attribute paths - for the GetItem, Query and Scan
operations.
There is a fourth read operation - BatchGetItem, and it supports
ProjectionExpression too. We tested BatchGetItem + ProjectionExpression in
test_batch.py, but this only tests the basic feature, with top-level
attributes, and we were missing a test for nested document paths.
This patch adds such a test. It is still xfailing on Alternator (and passing
on DynamoDB), because attribute paths are still not supported (this is
issue #5024).
Refs #5024.
