Schedule CRD got removed after Schedule template created on helm-2.16.10

[Vladikamira]

What steps did you take and what happened:
enabled installCRDs: true flag after upgrade helm-2.12.x to helm-2.16.10, and during helm upgrade --install step getting schedule CRD deleted after schedule template being created, which lead to removing schedule template.
As I understand, it because of post-upgrade hook in CRD

What did you expect to happen:

get Schedule template not deleted after install

Anything else you would like to add:
Here is part of tiller log which shows that we install schedule template first, and delete/install CRD after that
