SipNoteUpdateView.get_form() and SipNoteForm.__init__() seemingly do the same thing

[toraritte]

Both set the input labels of the same form to the same values. If I interpreted the evaluation steps when stepping through a request with PDB:

• SipNoteForm is only used when a new note is created.

• When a SIP note is updated via SipNoteUpdateView, it doesn't use the existing SipNoteForm (for some reason), but creates a generic form from scratch on the spot instead, which, confusingly, will also be called SipNoteForm. (The fully qualified names will differ though: django.forms.widgets.SipNoteForm instead lynx.forms.SipNoteForm.)
