Comment (by dgoulet):

 Code update. I've addressed most of Nick's review. Few things that we need
 to figure out in there.

 An `_02` branch has been created which squashes the gazillion fixup
 commits in the `_01` branch. The git diff is empty so that is that.

 I've pushed two new commits on both branches obviously. One that makes us
 send back the DESTROY cell right after we get the CREATE instead of "at
 the next cell on that circuit".

 Second commit is unit tests that asn did that I've ported.

 The `_01` merge request is still alive and kicking for discussions:
 Branch: `ticket24902_029_01`

 The `_02` merge request on if you prefer review a fresh branch:
 Branch: `ticket24902_029_02`
