Bug 18058: Allow borrower_message_preferences to be truncated

Browse source 
borrower_message_preferences cannot be truncated because of the foreign.
DBMS fails with
  "Cannot truncate a table referenced in a foreign key constraint"

To avoid that we should remove the FK check and truncate the other table
as well.

I am wondering if we really need a truncate here
  DELETE FROM borrower_message_preferences;
should do the job, but leave it as it because of the param name.

Test plan
  perl misc/maintenance/borrowers-force-messaging-defaults --doit --truncate
Should no longer raise the error message
