No Jenkins job is setup to build the testing branch after freeze

We’re now frozen, and I see no job to build the testing branch. Seems that something is wrong in our algorithm that detects what should be built.

This is an urgent problem during the 1.5 release process, because in my understanding, even if I added such a job myself, it would be deleted on next jobs update.

Feature Branch: pythonlib:bugfix/9925-add-testing-branch-at-freeze-time
