SI-5824 Fix crashes in reify with _*
Reification crashes if "foo: _*" construct is used. This happens besause type tree is represented either with TypeTree, or with Ident (present case), and `toPreTyperTypedOrAnnotated' only matches of the former. The fix is to cover the latter too. A test is included.
