This option allows you to add preferences only when they are not yet
present. In other words: skip patrons that already set their prefs.
Test plan:
[1] Delete all borrower messaging prefs for a patron.
[2] Run borrowers-force-messaging-defaults.pl -no-overwrite -doit
Verify that the patron now has default msg preferences.
[3] Change his settings and make them non-default.
For instance, increase days in advance.
[4] Run borrowers-force-messaging-defaults.pl -no-overwrite -doit
Verify that the patron still has the non-default settings.
[5] Run borrowers-force-messaging-defaults.pl -doit
Verify that the patron msg prefs have been overwritten.
