Bug 25677: Checkbox options for EDI accounts cannot be enabled

Checking any of the checkboxes in the EDI Account editor does nothing.
They always remain set to "off".

Test Plan:
1) Browse to edi_accounts.pl
2) Create a new EDI account, check all the checkboxes
3) Edit the account, note none of the checkboxes are checked
4) Apply this patch
5) Repeat steps 1-2
6) Note the checkboxes remain checked
