Issue Description:

Contrary to Darwin Foundation, CLF URLSession crashes when downloading a file through a custom URLProtocol and no temporaryFileURL property is set:

Fatal error: Unexpectedly found nil while unwrapping an Optional value: file /home/buildnode/jenkins/workspace/oss-swift-package-linux-ubuntu-18_04/swift-corelibs-foundation/Foundation/URLSession/URLSessionTask.swift, line 855
