Fix SQL mode check to respect custom connection parameters

The get_current_sql_modes() method was ignoring custom connection
parameters like --host, --dbuser, and --defaults, causing authentication
failures. Now it properly passes these parameters through when checking
SQL modes.

This fixes the reported issue while maintaining WordPress SQL mode
compatibility for queries that need it.
