Fix a couple of type name collisions (#4419)

Browse Source 
PEP 484 indicates that all type annotations within a stub file are supposed to be considered forward references even if they are not quoted. This means a type checker needs to use scope-based symbol resolution without regard for code flow order. Lookups will find same-named symbols within the same scope even if they are declared after the type annotation. This change fixes a couple of cases where this occurs and confuses pyright.
