Subject: [PATCH] Add scripted test for closing classloaders

https://github.com/sbt/sbt/issues/5075 reports that sbt 1.3.0 has a
regression for in process run. In sbt 1.3.0, we close the classloader
that invokes the main method before all of the daemon threads complete.
This adds a scripted test that fails due to this regression.
