Fix custom errors thrown as 500 (#6238)

We call convertExceptionToGraphQLError in the exception handler for http
exceptions but we don't take into account those that already are
graphqlErrors and because of that the logic of convertExceptionToGraphql
is to fallback to a 500.
Now if the exception is a BaseGraphqlError (custom graphql error we
throw in the code), we throw them directly.
