Table entity string IDs should be 255

Supporting entity reference fields OOTB is a basic feature, so I'd classify this as a bug. Thanks for filing the ticket and providing the MR. (special thanks for the update tests! 👏 )

This is causing a fatal error when running the update hook on sites that have been using Entity Usage since version 2.0-alpha4 or older. In those early versions the target_id_string column still allowed NULL values. Now the table is updated to mark the column as NOT NULL which throws a fatal error when the NULL values are encountered. Created followup issue to address this: 🐛 Fatal database error when updating to 2.0-beta9: "Invalid use of NULL value" Fixed .
