An additional warning saying "tc-log cannot be enabled" is emitted when InnoDB is installed at runtime on mysqld built with wsrep-patch (-DWITH_WSREP=ON). This happens because, installing InnoDB increments the total number of 2pc-capable engines and with wsrep-patch already enabled - the total count goes >1. Even though, this condition is sufficient to enable tc-logging, it is not permitted at runtime, and thus the warning. Updated the testcase to avoid the warning.
