If there are no known backups, backup-list dumps a traceback instead of a useful message.

```python
Traceback (most recent call last):
File "/usr/local/bin/wal-e", line 9, in
load_entry_point('WAL-E==0.5.9', 'console_scripts', 'wal-e')()
File "/opt/python2.7/lib/python2.7/site-packages/WAL_E-0.5.9-py2.7.egg/wal_e/cmd.py", line 287, in main
backup_cxt.backup_list(query=args.QUERY, detail=args.detail)
File "/opt/python2.7/lib/python2.7/site-packages/WAL_E-0.5.9-py2.7.egg/wal_e/operator/s3_operator.py", line 94, in backup_list
w_csv.writerow(backup_info)
_csv.Error: sequence expected
