[Flight Reply] retain listeners when resolving models with existing listeners (#29207)

In #29201 a fix was made to ensure we don't "forget" about some
listeners when handling cyclic chunks.
In #29204 another fix was made for a special case when the chunk already
has listeners before it first resolves.

This implements the followup fix for Flight Reply which was originally
missed in #29204
