This fixes a panic if this code was ever called on an element with a class
attribute in a non-null namespace. In this case, the attribute would not have
been parsed into a list of tokens, so value_tokens_forever() would have
returned None.
However, this function is, as far as I can tell, never called, because of the
way selectors are evaluated in layout. ('Return the selectors that match this
node' rather than 'return the nodes that match this selector'; the latter
uses only each_class.)
