Miek Gieben 024f56682d middleware/chaos: fix version (#669)
* middleware/chaos: fix version

Move the version setting into a init function so it is done early. Then
tweak the setup code for chaos a bit to correctly pick this version up.
Add an integration test to pick this up in the toplevel test/ directory.

Fixes #667
