TMP: Test solidus_support without flickwerk

solidus_support 0.11.0 introduced flickwerk for patch
loading. Somehow this messes with the zeitwerk autoloader
and things acting weird (inflections broken, wrong constant
module nesting, etc.)

Revert happens in solidusio/solidus_support#93

This commit is for testing that the revert works.
