[DanielMuller-TN]

Forced unicode encoding for lxml XML fragment validation output to resolve certification authentication request signing TypeError failures.

Relates to bug #339

[akinross]

ran test locally successful with rebased code

This is missing a specific test case in the aci_rest test cases that uses XML + Certificate Authentication so we don't reintroduce this issue in the past.
