TUN-6725: Fix testProxySSEAllData

This test was failing on Windows. We did not catch it before because our
TeamCity Windows builds were ignoring failed unit tests: TUN-6727

 - the fix is implementing WriteString for mockSSERespWriter
 - reason is because cfio.Copy was calling that, and not Write method,
   thus not triggering the usage of the channel for the test to continue
 - mockSSERespWriter was providing a valid implementation of WriteString
   via ResponseRecorder, which it implements via the embedded mockHTTPRespWriter
 - it is not clear why this only happened on Windows
 - changed it to be a top-level test since it did not share any code
   with other sub-tests in the same top-level test
