Try to harden insert-conflict-specconflict against autovacuum.

Browse Source 
Looks like guaibasaurus had a autovacuum running during the
controller_print_speculative_locks step (just added in
43e08419708). Which does indeed seem quite possible.

Avoid the problem by only looking for the backends participating in
the test.
