- remove some remaining sys.modules shenanigansrel_0_7b1

- The "sqlalchemy.exceptions" alias in sys.modules
has been removed.   Base SQLA exceptions are
available via "from sqlalchemy import exc".
The "exceptions" alias for "exc" remains in
"sqlalchemy" for now, it's just not patched into
sys.modules.
