Bug and debug

If you can't follow a new user and have this error:

2022-04-23T19:26:12.639285Z  WARN plume::routes::errors: Db(DatabaseError(UniqueViolation, "duplicate key value violates unique constraint \"follows_unique_ap_url\""))

You might have an empty field in your database:

plume=> select * from follows where ap_url='';
  id  | follower_id | following_id | ap_url
------+-------------+--------------+--------
 2118 |          20 |          238 |
(1 row)

Simply set the ap_url as follows:

plume=> update follows set ap_url='https://plume.deuxfleurs.fr/follows/2118' where id=2118;
