When migrating repositories with reactions with deleted users, the original author id may be -1. This means that it is possible to end up attempting to create multiple reactions with the same [ Type, IssueID, CommentID, UserID, OriginalAuthorID ] thus breaking the constraints. On SQLite this appears to cause a deadlock but on other dbs this will cause the migration to fail. This PR extends the constraint to include the original author username in the constraint.
