Title: Imported mixin generates wrong relative path for unquoted path

When relative URLs are on, and there's an image referenced via `url(...)`,
if the URL is unquoted, the generated CSS duplicates the base path.
This is a failing test which demonstrates the problem. It fails in 1.4.1,
as well as in the 1.5.0-wp branch.
