Don't move partial classes inside Twig attributes

[thecrypticace]

This is the same as #164 but for Twig / Melody.

Given:

<div class="sm:p-4 p-2 text-{{ i }}"></div>

Before PR (incorrect):

<div class="text- p-2 sm:p-4{{ i }}"></div>

After PR (correct):

<div class="p-2 sm:p-4 text-{{ i }}"></div>

Fixes #183
