[tests] test_archive_message_unserializable doesn't work properly in python3.7
Hi,
I'm not sure if this is python3.7 specific or all python3 thing, but the serialization does succeed in the mentioned test, and hence the test fails because the potential raised error isn't accurate.
(In my case, it tries to post the message via hyperkitty which is down because I run the tests in a chroot).
Cheers!
