Django 2.1.6 risolve un problema di sicurezza e un bug in 2.1.5.

## CVE-2019-6975: Memory exhaustion in `django.utils.numberformat.format()`

If `django.utils.numberformat.format()` – used by `contrib.admin` as well as the `floatformat`, `filesizeformat`, and `intcomma` templates filters – received a `Decimal` with a large number of digits or a large exponent, it could lead to significant memory usage due to a call to `'{:f}'.format()`.

To avoid this, decimals with more than 200 digits are now formatted using scientific notation.

### Correzioni di bug

- Made the `obj` argument of `InlineModelAdmin.has_add_permission()` optional to restore backwards compatibility with third-party code that doesn’t provide it (#30097).
