fix: allow async errors to bubble to AsyncIterable list items

[yaacovCR]

Previously, async errors from further down in the tree would bubble to the parent list rather than the individual item.

This change also fixes the test so that completeValue rejects for the AsyncIterable itself -- the true intent of this test -- and not just for the nested object.
