Fix for the test galera.galera_UK_conflict

mtr test galera.galera_UK_conflict, has rather distorted logic in test scenario 2.

The test would fail always with:

CURRENT_TEST: galera.galera_UK_conflict
mysqltest: In included file "./include/galera_wait_sync_point.inc":
included from /home/seppo/work/wsrep/mariadb-server/mysql-test/suite/galera/t/galera_UK_conflict.test at line 216:
At line 3: query 'SET SESSION wsrep_on = 0' failed: 1179: You are not allowed to execute this command in a transaction

This happens because wait_condition is called in wrong connection (node_1, which is excuting MST transaction)

This test is fixed by using contl connection for wait contdition check, and new result is recorded as well
