Refine Kolibri 0.12.0+ to remove red/pink warnings during (re)install

[holta]

@arky & all let's try to work together to remove this very final red/pink error (warning) for Kolibri 0.11.0 in advance of IIAB 6.7's release in December, if possible!

Ref: #1130

[arky]

@holta I have patched latest Kolibri development branch to handle this ValidationError exception with a warning. These changes would be shipped with next release.

Please close this bug as fixed whenever it is appropriate.

Fantastic news.

Is a PR possible in January possibly?

@holta This is a upstream bug, there is no patch necessary here.

Got it. Should we consider failed_when: false for IIAB 6.7, as was done with PR #1396 ?

(I'm fine either way!)

[holta]

Is there any partial/substantial progress here 7 months later?

Done (certainly good enough!) as Kolibri playbook was cleaned up & refactored with Benjamin Bach in September/October.
