Include OriginalAuthor in Reaction constraint (#13505)
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.

Fix #13271
