27805	"ClearableFileInput's ""Clear"" checkbox on model fields with a default doesn't work"	Mario J. Barchéin Molina	Tim Graham	"Checking 'clear' in a FileField and saving the ModelForm doesn't set None in model's attribute. 

This is broken from 1.10.2 to 1.10.x and 1.11a1. Works in 1.9.x and 1.10.1

I attach a simple project ""polls"" with only one model (TestModel) and admin zone. To reproduce the problem:

1) Log in in admin zone in http://localhost:8000/admin/polls/testmodel/ with user ""admin"" and password ""adminadmin""
2) Create a new ""Test Model"" with an image
3) Edit the created ""Test Model"" instance, check ""clear"" checkbox and submit form

The expected behaviour is having model with no image but this doesn't happen.
