Summary

Fixes issue described in #30399: A default value on the
inheritance column prevented child.becomes(Parent) to return
an instance of Parent as expected, instead it returns an instance
of the default subclass.

The change was introduced by #17169 and it was meant to affect
initialization, alone. Where Parent.new is expected to return
an instance of the default subclass.

After the original issue was marked as stale I've confirmed this is still an issue in Rails 5.1.4 and 5.2.0.beta2. I rebased this PR to make it easier for reviewers.

Looks good to me. Can you squash your commits into one?
