DD: update the rendering of the 'named' line

the template's rendering of a `named` line was incorrectly wrapping
strings with underscores in single quotes, whereas the quotes would only
be necessary for strings with hyphens.

the regex detection of a hyphen also duplicates logic found in the
`snake_name` method. Rather than essentially checking to see that
`snake_name` would have performed a transformation of the string by
duplicating the regex of the transformation, just compare `@name` and
`@snake_name` for equality.
