MDEV-13255 main.status failed in buildbot

Browse source 
Test fails sporadically and very rarely on this:
```
let $org_queries= `SHOW STATUS LIKE 'Queries'`;
SELECT f1();
CALL p1();
let $new_queries= `SHOW STATUS LIKE 'Queries'`;
let $diff= `SELECT SUBSTRING('$new_queries',9)-SUBSTRING('$org_queries',9)`;
```
if COM_QUIT from one of the earlier (in the test) disconnect's
happens between the two SHOW STATUS commands.
Because COM_QUIT increments "Queries".

The directly previous test uses wait_condition to wait for
its disconnects to complete. But there are more disconnects earlier
in the test file and nothing waits for them.

Let's change wait_condition to wait for *all* disconnect to complete.
