Test language/src/NamedParametersWithObjectPropertyNamesTest.dart contains several
methods that have optional named arguments that start with and underscore.

The language spec says:

 It is a compile-time error if the name of a named optional parameter begins with an ‘_’ character.

Moved issues with specific language tests to the area "Language". These tests should be fixed by the language deciders and implementers.

This can be closed. tests/language/named_parameters_with_object_property_names_test.dart no longer has any named optional parameters that begin with a _.
