[Twisted-web] getChild in python3

[Tom Most]

Hi Nathaniel,

The string 'bug' needs to be a bytestring, b'bug'. This is indeed a bug, but Twisted 19.7.0 will at least generate a deprecation warning about it. A future version of Twisted will throw an exception (once the deprecation period has passed).
