sql_browser_ui_test: adjust test for mariadb >= 10.3.38

For such query with multiple SELECT since mariadb 10.3.38, the error is
no longer a "commands out of sync" ProgrammingError, but a simple SQL
error during the parsing step - and nothing is executed.

Adjust the test to just expect "rror" which would match Error (from
ProgrammingError) and "error" from ("you have an error in your SQL syntax")
