Bug 19344: Reorder lang and login_attempts in the [deleted]borrowers tables

Bug 19344: Reorder lang and login_attempts in the [deleted]borrowers tables

Due to a bad rebase, the borrowers and deletedborrowers table structure
may different from a new install and upgraded install
For new installs, the order was: lang, login_attempts
For upgraded installs, it was lang, last_seen, login_attempts

After this patch, the order must be:
- last_seen
- lang
- login_attempts
