Moved method getSelectDefault from filter_select to TableMetaModelFilterSetting.

This was forgotten in 0d0703af7f37023e1ede9cff85353e31fe6dae2c and should also
fix issue #157 along the way.
Removed redundant check if metamodel object instance is available.
Language strings: "tags" was being used instead of "values" leading to confusion when configuring
select filters.
