Ran this query to find pastes with missing edges:
```
select id, FROM_UNIXTIME(p.dateCreated) from pastebin_paste p LEFT JOIN edge ON edge.src = p.phid AND edge.type = 25 WHERE edge.dst IS NULL order by id;
```
Ran the migration.
Verified the edges were fixed.
Viewed one of the affected pastes, things now worked properly.
