Admin page gives errors

[cecilia-donnelly]

At openhmis/admin, I was able to log in but then the following error popped up:
DataTables warning: table id=DataTables_Table_0 - Requested unknown parameter '1' for row 0, column 1. For more information about this error, please see http://datatables.net/tn/4

I'm pretty sure this is because our "organization" and "coc" fields are now foreign keys to other tables instead of strings (or possibly because they have been renamed to organizationId and coCId). It should be straightforward to fix.
