In order for web.Wrap to be able to detect if a response has been written we need to wrap any non-context.ResponseWriters as a such. Otherwise responses will be incorrectly detected as non-written to and handlers can double run. In the case of GZip this handler will change the response to a non-context.RW and this failure to correctly detect response writing causes fallthrough and a NPE. Fix #19839 Signed-off-by: Andrew Thornton <art27@cantab.net>
