Answer 1

I add another answer to this question has I found the solution by mixing some of them.

1. Most voted answer is the main solution, but it is also important to
2. Add the entry suggested by this answer. Finally
3. Follow the comment from @feradz in most voted answer: "delete the .min.css version -- it was causing the optimizer to not generate a minified version with the correct path"

Last point is the key of all: distributed "min" versions of the js files, does not follow the "CssRewriteUrlTransform" rules. So, manually deleting bootstrap.min.css, font-awesone.min.css definitively solved the issue.
