Issue Description:

The following test case fails to refactor to async with the error message cannot refactor complex case conditions. Binding response as case .success(let response) works around the issue.

func fetch(_ completion: (Result<Int, Error>) -> Void) {}

// RUN: %refactor -convert-to-async -dump-text -source-filename %s -pos=%(line+1):3
func execute() {
    fetch() { (result: Result<Int, Error>) in
        switch result {
        case let .success(response):
            print(response)
        case .failure(_):
            break
        }
    }
}
