Errors with SQLAlchemy 1.4

[magical]

Attempting to run pokedex setup when using SQLAlchemy 1.4 throws an error and spews a bunch of warnings.

/home/travis/virtualenv/python3.7.1/lib/python3.7/site-packages/sqlalchemy/orm/relationships.py:3454: SAWarning: 
  relationship 'Language.names_local' will copy column languages.id to column language_names.language_id, 
  which conflicts with relationship(s): 'Language.names' (copies languages.id to language_names.language_id).
  If this is not the intention, consider if these relationships should be linked with back_populates, or if viewonly=True
  should be applied to one or more if they are read-only. For the less common case that foreign key constraints
  are partially overlapping, the orm.foreign() annotation can be used to isolate the columns that should be written towards.
  The 'overlaps' parameter may be used to remove this warning.

Using this patch the tests pass with sqlalchemy 1.4, while maintaining compatibility with 1.0-1.3. Unfortunatly the Query._execute_and_instances method doesn't seem to be subclassable anymore, and the docs suggest using do_orm_execute instead.

The warnings are still there, but silencing them with viewonly=True should be safe to do (the data is never modified outside of the setup/load/dump functions, is that correct?)
