PR #7531 resolved issue #7433 by updating `ErrorDetails.__eq__` to correctly
handle the `NotImplemented` case. However, Python 3.9 continues to issue the
following warning:
DeprecationWarning: NotImplemented should not be used in a boolean context
This is because `__ne__` still doesn't handle the `NotImplemented` case
correctly. In order to avoid this warning, this commit makes the same change
for `__ne__` as previously made for `__eq__`.
The test suite raises warnings when tested against Python 3.9
`DeprecationWarning: NotImplemented should not be used in a boolean context`
Where `r` returns `NotImplemented` then this change returns `NotImplemented` first to avoid the comparison test.
On Python 3, the ugettext functions are a simple aliases of their non-u
counterparts (the 'u' represents Python 2 unicode type). Starting with
Django 3.0, the u versions will be deprecated.

This adds `__eq__` to handle `code` in comparisons.
When comparing an ErrorDetail to a string (missing `code` there) the
ErrorDetail's `code` is ignored, but otherwise it is taken into account.
Pull up method from subclass to superclass
The call was added in 426547c61c
to allow for dict-style arguments to ValidationError but does not
apply to other APIException descendants.
Since `str` objects are immutable, appending to existing `str` creates
in fact a new `str` instance.
Thus `ErrorDetail.detail.code` attribute is lost after `str` concatenation operation.
This addresses the changes requested in #2054 and allows for custom messages that do not necessarily require a string formatter be present in the detail message.
