It should only unset the data if you are creating the User and it's missing
the 'file' key. If you are updating, you shouldn't *need* the 'file' key.
That said, you can probably get away with passing an empty (or a path to a
default image) file key when you are creating the User using a hidden
field. This should allow the coupler to continue with the save. This may
save some empty garbage data that is probably unwanted.
The other solution would be to detach the Coupler behavior at runtime when
you don't want it to "force" you to have an image.
The whole point of the Coupler is to tightly couple the physical image to
the record, so if the image doesn't exist neither should the record. I tend
to create a separate table for attachments for this very reason. A user
should be allowed to exist without an image.
