Currently `BaseInlineFormSet` appends the FK name for the formset to the
fields for the form `Meta` every time `add_fields` runs, so with you end
up with N fields where N - 1 are duplicates. As each form is instantiated
it'll see a different version of the list.
Example based on `tests/inline_formsets/tests.py`:
{{{
>>> poet = Poet.objects.create(name='test')
>>> poet.poem_set.create(name='first test poem')
>>> poet.poem_set.create(name='second test poem')
>>> poet.poem_set.create(name='third test poem')
>>> PoemFormSet = inlineformset_factory(Poet, Poem, fields=('name',),
extra=0)
>>> formset = PoemFormSet(None, instance=poet)
>>> PoemFormSet.form._meta.fields
['name', 'poet', 'poet', 'poet']
}}}
