The "docker compose up -d database" doesn't work because it complains about it. Not sure what it did to start with.

resolves #9128
Problem
In the build command we want to be able to run unit tests first, before the model it tests, and skip the model if a unit test fails.
For selection purposes we want to keep the graph with the unit tests depending on the model. But for running the build command we want the opposite.
Solution
There were two alternatives for a solution here, and both of them have difficulties.
The most natural would be to change the graph to have the unit tests before the model, but that would be very strange for selection semantics, so we would have to have two separate dags, one with unit tests after the model and another with unit tests before the model. We could have modified the selection dag to look like the required execution dag, but that would be fairly complicated since every unit test would have to be inserted as parent of the model and itself be a child of every one of the model's parents. There were also concerns about performance, since adding test_edges to the build dag made things slower, and this solution would have increased the size of the dag even more.
The other alternative, and the one that's implemented here, is to insert the execution of the unit tests in before the execution of the model. This requires some refactoring of the way we "run" the job_queue, and some somewhat inelegant hacking of the build code. But is probably easier to understand than the graph hacking solution and doesn't have the performance risks.
