Out of range value for column 'events' in wmbs_file_details
While draining submit5, I noticed there were a couple of LQE stuck in Available/Acquired not going through the wmbs preparation. Checking the WorkQueueManager log brings me to this traceback [1].

The table schema is
```
MariaDB [wmagent]> desc wmbs_file_details;
+-------------+--------------+------+-----+---------+----------------+
| Field       | Type         | Null | Key | Default | Extra          |
+-------------+--------------+------+-----+---------+----------------+
| id          | int(11)      | NO   | PRI | NULL    | auto_increment |
| lfn         | varchar(700) | NO   | UNI | NULL    |                |
| filesize    | bigint(20)   | YES  |     | NULL    |                |
| events      | int(11)      | YES  |     | NULL    |                |
| first_event | bigint(20)   | NO   |     | 0       |                |
| merged      | int(1)       | NO   |     | 0       |                |
+-------------+--------------+------+-----+---------+----------------+
6 rows in set (0.00 sec)
```

which has a clear inconsistency between `events` and `first_event` as well.

And for the record, this was the GQE mask:
```
"Mask":{"LastRun":1,"FirstRun":1,"inclusivemask":true,"runAndLumis":{},"LastEvent":2662796000,"FirstEvent":1,"LastLumi":1000,"FirstLumi":1}
```
