MediaWiki does not use foreign keys in the database schema
Additional changes to the schema:
- Mysql and sqlite creates index for each foreign keys, keep the index
to allow fast joins with this columns by explicit statement on new
wikis
- Explicit create statement for the UNIQUE index on column
eps_token_sha256 to make the index more visible on the sql file
- Rename existing index to match the prefix for existing indexes
