Adding a TextField that has an unhashable default fails with MySQL, for
example with `{}` as the default:
{{{
Traceback (most recent call last):
[...]
File "[...]/django/db/backends/mysql/schema.py", line 53, in add_field
if self.skip_default(field) and field.default not in {None,
NOT_PROVIDED}:
TypeError: unhashable type: 'dict'
}}}
