remove __getattr__ from root

Removed ``__getattr__()`` rule from ``sqlalchemy/__init__.py`` that
appeared to be trying to correct for a previous typographical error in the
imports. This rule interferes with type checking and is removed.

Fixes: #12588
Change-Id: I682b1f3c13b842d6f43ed02d28d9774b55477516
