Patch mysql creation policy to handle the "utf8mb4" facility. This appears tricky but it's necessary
due to the conception of "extended utf-8" in mysql. If we do not patch, the mysql backend cannot index
``VARCHAR(255)`` fields !
see <http://bd808.com/blog/2017/04/17/making-django-migrations-that-work-with-mysql-55-and-utf8mb4/>
for explanations
