Would love to do this, but where is `.form` defined?

I am looking, for example, at https://github.com/dimagi/couchforms/blob/master/couchforms/models.py#L98 and https://github.com/dimagi/couchforms/blob/master/couchforms/models.py#L141

Is this the wrong code? Am I missing something? Are you asking me to do the rename?

A quick grep does not turn up anything obvious, nor even does PyCharm have any good suggestions (and even if it did, code that requires an IDE to be legible is bad code)

If a `.form` property is magicked onto the obj in some way other than being simply legible in its definition, then I'd rather leave this code clear until that can be corrected.
