Django 1.11.12 fixes two bugs in 1.11.11.

## Correction de bogues

- Fixed a regression in Django 1.11.8 where combining two annotated `values_list()` querysets with `union()`, `difference()`, or `intersection()` crashed due to mismatching columns (#29229).
- Fixed a regression in Django 1.11 where an empty choice could be initially selected for the `SelectMultiple` and `CheckboxSelectMultiple` widgets (#29273).
