Fix rabbit_stream_queue:get_counters querying writer last

`rabbit_steam_coordinator:stream_overview/1` returns the member in
different format than `members/1`, resulting in `is_writer/1` never
matching. This was changed in PR #6440. This prevents getting counters
from stream writer last as intended by PR #6442.
