Address race condition in InitializeBackendData (#6285)
Sometimes in CI our isolation_citus_dist_activity test fails randomly
like this:
```diff
step s2-view-dist:
SELECT query, citus_nodename_for_nodeid(citus_nodeid_for_gpid(global_pid)), citus_nodeport_for_nodeid(citus_nodeid_for_gpid(global_pid)), state, wait_event_type, wait_event, usename, datname FROM citus_dist_stat_activity WHERE query NOT ILIKE ALL(VALUES('%pg_prepared_xacts%'), ('%COMMIT%'), ('%BEGIN%'), ('%pg_catalog.pg_isolation_test_session_is_blocked%'), ('%citus_add_node%')) AND backend_type = 'client backend' ORDER BY query DESC;

I intended to fix this with #6263, but the fix turned out to be
insufficient. This PR tries to address the issue by setting
distributedCommandOriginator correctly in more situations. However, even
with this change it's still possible to reproduce the flaky test in CI.
In any case this should fix at least some instances of this issue.
In passing this changes the isolation_citus_dist_activity test to allow
running it multiple times in a row.
