JobAccountant crashes while inserting into wmbs_file_details (data too long)
**Impact of the bug**
Happening only on submit6 for now.

**Describe the bug**
There is a job that produced a LFN longer than what's the current limit of the `lfn` column in `wmbs_file_details`, which is set to 700 chars at the moment.

Here is the file name (715 chars in total):
```

```

This problem goes along the same lines as what got fixed in this PR:
https://github.com/dmwm/WMCore/pull/9243

**How to reproduce it**

**Expected behavior**
We need to check what are the tables storing an LFN and bump that column to a larger value (I guess 1250 chars is good enough).

**Additional context and error message**
For the record, here is the - misleading due to the first value in the tuple - traceback:
