Test execution retry logic broken for tst_opcua:AbsoluteNodeTest

tst_opcua:AbsoluteNodeTest is reported flaky in QTBUG-104418

The system tries to execute a test 5 times before declaring it failed.
This doesn't work properly for the tst_opcua, it fails on "Could not find the following test functions":
