Update taiga does not work

[JanoschDeurer]

If taiga is updated e.g. because someone updated it in the docker image you generate, the database migration is not executed. You can do this by hand by entering the container, but it would be great if this would happen automatically.

Tags would be helpful.
Then the update could be done at a desired time and not seemingly randomly.
Git Hashes are (IMHO) a good enough docker image tag.
