The commit (2d526f9 Updating models and imports for Django 2.2 upgrade.)
has added on_delete=models.deletion.CASCADE on the ForeignKeys such as
Branch and LayerBranch, which blocks the deletion of Branch or LayerBranch, e.g.:

Deleting the branch 'foo' would result in deleting related objects, but your
account doesn't have permission to delete the following types of objects:

Append
patch
machine
recipe
inc file

Refer to:
https://docs.djangoproject.com/en/4.1/ref/models/fields/#django.db.models.ForeignKey.on_delete

The CASCADE means that it needs remove "Append", "patch" and other objects, but
has_delete_permission returns False blocks the deletion, so we need remove the
local has_delete_permission() to make Branch or LayerBranch can be deleted. The
django's default has_delete_permission() will be used after removal.
