Bug #26104 Bug on foreign key class constructor
Check that ref_columns is initalized correctly in the constructor
and semantic checks in mysql_prepare_table work.
We do not need a storage engine that supports foreign keys
for this test, as the checks are purely syntax-based, and the
syntax is supported for all engines.
