Enable AsyncConnectionImplAppendableTest.ResumeAppendableObjectUploadWithChecksum in Windows

Had to disable this test as it failed to compile using MSVC

Start by locating AsyncConnectionImplAppendableTest.ResumeAppendableObjectUploadWithChecksum and inspect why it does not compile with MSVC on Windows. Compare the test and its build configuration with the surrounding appendable object upload tests; done means the test compiles and runs successfully on Windows without being disabled.
