Fix class_desc_deselect handling of @GlobalScope.X links
Fix class_desc_deselect handling of @GlobalScope.X links

Fix bug where links to class enums and class constants of the form @GlobalScope.X were broken.

For an enum or constant with name "example_name", links of both forms @GlobalScope.example_name and example_name will now be correctly handled, including where example_name contains "." (e.g. Variant.Type).
