Boolean field default value is not applied when request is made using form data

[Gomes117]

Minimum code for reproduction:

class Test(models.Model):
    name = CharField(default="Bob", max_length=255)
    is_person = BooleanField(default=True)

I would expect that with this code when I send an empty POST I will get an instance of Test with name = Bob and is_person = True. If the request is JSON encoded it works as expected, but if I send it as multipart/form-data only name is set correctly, is_person is set to False.

After some debugging I tracked it to Field.get_value() specifically line 427 return self.default_empty_html. In the case of CharField empty will be returned which will then lead to the default value being used. But for a BooleanField default_empty_html is False which will be set as value and the default value won't be used.

I feel like defaults should work the same regardless what type of field is used or what kind of request was made.
