    Add a test for unsetting Delete-on-Close before the close by DoC opener.
    
    Windows semantics says that any unset of Delete-on-Close before the client
    that opened for Delete-on-Close closes the file is silently ignored and the file
    is still deleted on the last close. This test tests that in a single open case.
