Fix all the `asBuilders()` functions

[rock3r]

They used to return a list made up of the same builder repeated n times, where n is the size of the source list, instead of n builders.

This requires a number of internal (non API breaking) changes to all validating builders.

💛 - Coveralls

[rock3r]

Just a quick note: most of the new lines are equals/hashcode/toString in the validating builders. Unfortunately, this brings down coverage, but I'm not going to test autogenerated code...

Oh boy, this is a pretty severe issue. Good that you've notices this!

The coverage impact is a downer of course, but you're right of course, there is no point in testing generated code.

LGTM 👍

v1.1.0 is ready to be shipped from my perspective.
