Move Analyze and ClassToAPI specifications
The b0a8a91 merge commit didn't resolve merge conflicts for AnalyzeSpecification.scala and for ClassToAPISpecifaction.scala. This commit oves them to the right subprojects and adapts them to Scalatest APIs. Both specifications depend on TestCallback so it had to be moved to a subproject commonly referenced. I've moved it to the compiler-interface subproject. As a consequence, I had to add a dependency on scala-library in `test` configuration to compile TestCallback written in Scala.
