CLN: Remove incorrect check, comment, rename
cc @jorisvandenbossche 
@jorisvandenbossche did i miss anything? Given the confusion / discussion around it, I would keep *some* comment explaining why you set the name after finalize (instead of passing it to `_constructor`). At least for me it would not be directly obvious. Hello @jbrockmendel! Thanks for updating this PR. We checked the lines you've touched for [PEP 8](https://www.python.org/dev/peps/pep-0008) issues, and found:



There are currently no PEP 8 issues detected in this Pull Request. Cheers! :beers:
