Subject: [PATCH] add fixup_1.sql, which corrects the UNIQUE error on
 user_contacts

- The user_contacts table contained an incorrect UNIQUE constraint
  on wa_jid that meant only one user of the bridge could have any
  given whatsapp user in their contacts.
- This is fixed in fixup_1.sql, which should be applied over schema.sql.
