test_type_conversions_hive3 silently passes because of wrongly defined test dimensions

test_type_conversions_hive3 silently passes because we are not creating the test dimenstion for query option orc_shema_resolution correctly.

Instead of:

cls.ImpalaTestMatrix.add_dimension(ImpalaTestDimension('orc_schema_resolution', 0, 1))

We should do the following:

add_exec_option_dimension(cls, 'orc_schema_resolution', [0, 1])

We should fix how we add the test dimension, and also fix the underlying bug it reveals.
