Default themes always trump their pretenders. Even though we are no longer keying by name, it is not a good experience to see multiple 'WordPress Default' themes when one was copied and had the directory renamed. This also keeps with the behavior of get_themes() (and the deprecated return value). see #20103.

Allow a default theme within a directory of wp-content/themes (e.g. 'somedir/twentyeleven') to be identified as a default theme.
