[SPARK-8910] Fix MiMa flaky due to port contention issue
Due to the way MiMa works, we currently start a `SQLContext` pretty early
on. This causes us to start a `SparkUI` that attempts to bind to 4040. Because
many tests run in parallel on the Jenkins machines, this causes port
contention sometimes and fails the MiMa tests.
Note that we already disabled the SparkUI for scalatests. However, the MiMa
test is run before we even have a chance to load the default scalatest
settings, so we need to explicitly disable the UI ourselves.
