These are the only cases 100% safe to apply the renaming of the
testcase class names to match the file names.
All other cases are not safe, because they are missing namespace

of modifications to core. See the issue for more details.
This change contains most of the output components required for
reports such as exporters, templates, AMD modules.
Also included are classes within the component table namespace which
are required for extending the dynamic table API.
