Lib has no attribute 'Cryptography_HAS_SSL_ST'

Observed behavior

I’m having this Lib has no attribute 'Cryptography_HAS_SSL_ST' when running kolibri command on Ubuntu 16.04

At the Ubuntu 18.04 this error will not reproduce with the same .deb installer.

@mrpau-richard Could you use this workaround to re-start the integration testing workflow on Ubuntu 16.04? Thanks!

@radinamatic thank you for the update! Unfortunately I think this is what we can try to temporarily eliminate the error for testing. I will create a PR for the fix asap
