[Flight / Flight Reply] Don't clear pending listeners when entering blocked state (#29201)

Fixes #29200

The cyclic state might have added listeners that will still need to be
invoked. This happens if we have a cyclic reference AND end up blocked.

We have already cleared these before entering the parsing when we enter
the CYCLIC state so we they already have the right type. If listeners
are added during this phase they should carry over to the blocked state.
