Types::BaseField accepts authorize after reload

What does this MR do?

When working on files in app/graphql the code correctly gets autoloaded.

However, the redefined Types::BaseField would never receive the .accepts_definition call, causing all queries after a reload to fail.

What are the relevant issue numbers?
