Fix mypy 0.930 issues

Removed errant "type: ignore".

Fixed issue with "fetch" call. This issue was the following:

Dict::get() and Dict::pop() have the following signature:

T.Callable[[_T, _U], _U | None] OR T.Callable[[_T], _U | None]

Note how the return type is _U here. When the fetch() function was
actually being called, it had the following signature:

T.Callable[[_T, T.List[_U]], T.Union[T.List[_U], _U]]

This is incompatible with the previous definitions. The solution is
simply to move where the default value is introduced if fetch() produces
None.
