Title: Fix unsigned columns in MySql

Unsigned column properties were never set. In consequence all migrations diff were trying to change the column definition when it was already changed. See symfony/symfony#3560

Would it be also nice to add some test to avoid regressions, but i don't know where it would be a nice place to put them.
