Setting some of the different AutoId types causes an error

[digitaldogsbody]

Expected behaviour:

Using the config pattern, I should be able to select the int-per-type AutoId config

Observed behaviour:

An AttributeError when trying to instantiate a new object: AttributeError: 'AutoId' object has no attribute '_type_translation'

Potential bug location(s):

Any other comments:

The AutoIdConfig class has a property called translation, and this is probably what is intended to be read (via self.config.translation, similar to the usage of the base_url property)
