Subject: [PATCH] test suite: clean server pids after server crashed (#12639)

when a server in the test suite crashes and is restarted by redstart_server, we didn't clean it's pid from the list.
we can see that when the corrupt-dump-fuzzer hangs, it has a long list of servers to lean, but in fact they're all already dead.
