Fix broken mssql integration tests

We were giving mssql server 10 seconds to start before creating the test
database. It now takes Github CI more than 10 seconds to start the mssql
server. Instead of increasing the leeway with guesses, this commit moves
the creation of test database from docker compose to the python test suite.
This allows the docker image to come up first and then create the DB
inside the test suite with proper retry mechanism that is already in
place.
