Child theme´s gulp file generates own child-theme.min.js and
child-theme.min.css files. Theme just loads this assets. Just the php
files are shared with parent theme from now on
The child theme loads it´s own css file and don´t need the parent
themes css. But it uses the parent themes inc/enqueue.php file which
register and enqueued the parent themes css file from the child themes
directory. Caused a 404 request. Fixed with this changes.
