submit on forms requires manual user specification

(this is also the same for the lookout forms)
when you add 'owner' to the fields in the form, you can submit the form, but you have to manually select the user from the dropdown
this despite the field for the model being owner = models.ForeignKey(settings.AUTH_USER_MODEL), which would seem to auto-select the user currently creating the model
fix the forms so that the 'owner' field is autopopulated as intended and hidden from the user interface
