Fix new subscribe mode test in reply-schemas-validator (#11939)

The reason is in reply-schemas-validator, the resp of the
client we create will be client_default_resp (currently 3):
```
client *createClient(connection *conn) {
    client *c = zmalloc(sizeof(client));
 #ifdef LOG_REQ_RES
    reqresReset(c, 0);
    c->resp = server.client_default_resp;
 #else
    c->resp = 2;
 #endif
}
```

But current_resp3 in redis-cli will be inconsistent with it,
the test adds a simple hello 3 to avoid this failure, test
was added in #11873.

Added help descriptions for dont-pre-clean option, it was
added in #10273
