MDEV-25693: SST failed due to incorrect connection address

Fixed bugs caused by inaccuracies in automatic merging
from other branches:

1) Authentication information is not removed from the connection
   address, which causes some tests to fail;
2) wsrep_debug=on should be replaced with wsrep_debug=1;
3) Added missing "connection" lines to test result file;
4) Some tests have been corrected for Galera 4.x (10.4+).
