0.12.9

Changes:
- Fix the bug where `kaserve` won't set up the database if it's missing (fixed [here](https://github.com/learningequality/ka-lite/commit/c95e8ff6bf0454c2389a7e029b757ac7e69b1f7b))
@jamalex any negative consequences if I move the Job update right down here instead of at the start of the command?
