Only fetch thread participation for events with threads. (#12228)
We fetch the thread summary in two phases:

1. The summary that is shared by all users (count of messages and latest event).
2. Whether the requesting user has participated in the thread.

There's no use in attempting step 2 for events which did not return a summary
from step 1.
