need Twisted 14 compatibility

[dawuud]

I noticed a while back that Foolscap doesn't fully support Twisted 14... This unit test, foolscap.test.test_promise fails :

[ERROR] Traceback (most recent call last):

See also ​https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=755339. There is a patch there that has been applied to the foolscap package in Debian {testing, unstable}, but I don't know whether it is correct.

Fixed (but not yet in a release) in ​https://github.com/warner/foolscap/commit/2eeabc61c2573652d7482d039644d62d782c2e3a.
