mysql: change collation of tag table
utf8mb4_unicode_ci considers that 'caché' is equal to 'cache' which can lead to attaching incorrect tags to entries. This issue is due to some unicode normalization done by MySQL. utf8mb4_bin makes no unicode normalization, letting wallabag to consider 'cache' and 'caché' as two different tags. We change the collation of the whole table as Doctrine does not support setting a collation on a column for a specific platform (it tries to apply utf8mb4_bin even for pgsql and sqlite).
