Push newly-added migrations; add migrations check in tox.ini

[niauah]

Migrations based on newly added changes in v1.6.2 should be added into released pyPI package.
A test django-admin makemigrations --check is added to remind future developers about this.

The class FileExtensionValidator is not supported before django 1.11, see https://docs.djangoproject.com/en/3.1/releases/1.11/#validators

Tests with lower versions failed as:

  File "/home/travis/build/fabiocaccamo/django-admin-interface/admin_interface/migrations/0021_file_extension_validator.py", line 17, in Migration

    field=models.FileField(blank=True, help_text='(.ico|.png|.gif - 16x16|32x32 px)', upload_to='admin-interface/favicon/', validators=[django.core.validators.FileExtensionValidator(allowed_extensions=['gif', 'ico', 'jpg', 'jpeg', 'png', 'svg'])], verbose_name='favicon'),

AttributeError: 'module' object has no attribute 'FileExtensionValidator'

@niauah thank you for reporting this.
There is no need to change the CI, I just forgot to push the migration file.
You can upgrade to 0.16.3 version.

Why not add a migration check to CI? I have something similar in my project and it ensures this kind of mistakes can’t happen 🙁
