#26597: Optparse for `noinput` and `interactive` can produce unwanted results
when
passed togeather

Because of the way options are parsed on:
https://github.com/django/django/blob/1.8.13/django/core/management/__init__.py#L106-L108
You can end up with the dictionary returning `.item` back in one of two
orders when you pass both `interactive` and `noinput`.
I assume this is present on other management commands, but I have not
tested them.
The following command:
`arg_options = {opt_mapping.get(key, key): value for key, value in
options.items()}`
can be run as:
`{{'noinput': 'interactive'}.get(key, key): value for key, value in
[('verbosity', 0), ('fake', True), ('list', True), ('fake_initial', True),
('app_label', 'tests'), ('noinput', True), ('interactive', False)]}`
or
`{{'noinput': 'interactive'}.get(key, key): value for key, value in
[('verbosity', 0), ('fake', True), ('list', True), ('fake_initial', True),
('app_label', 'tests'), ('interactive', False), ('noinput', True)]}`
leading to `interactive` being False or True, respectively.
The weird thing, is that `noinput` and `interactive` are opposite commands
and yet this code uses it for the same value. Makes my scripts sometimes
fail.
