Django 1.11.4 fixes several bugs in 1.11.3.

## Bugfixes

- Fixed a regression in 1.11.3 on Python 2 where non-ASCII `format` values for date/time widgets results in an empty `value` in the widget’s HTML (#28355).
- Fixed `QuerySet.union()` and `difference()` when combining with a queryset raising `EmptyResultSet` (#28378).
- Fixed a regression in pickling of `LazyObject` on Python 2 when the wrapped object doesn’t have `__reduce__()` (#28389).
- Fixed crash in `runserver`’s `autoreload` with Python 2 on Windows with non-`str` environment variables (#28174).
- Corrected `Field.has_changed()` to return `False` for disabled form fields: `BooleanField`, `MultipleChoiceField`, `MultiValueField`, `FileField`, `ModelChoiceField`, and `ModelMultipleChoiceField`.
- Fixed `QuerySet.count()` for `union()`, `difference()`, and `intersection()` queries. (#28399).
- Fixed `ClearableFileInput` rendering as a subwidget of `MultiWidget` (#28414). Custom `clearable_file_input.html` widget templates will need to adapt for the fact that context values `checkbox_name`, `checkbox_id`, `is_initial`, `input_text`, `initial_text`, and `clear_checkbox_label` are now attributes of `widget` rather than appearing in the top-level context.
- Fixed queryset crash when using a `GenericRelation` to a proxy model (#28418).
