Fix dependencies for Java 8

Adjust dependencies for Java 8's backward incompatible change in
javac:

  Area: Tools / javac
  Synopsis: Interfaces need to be present when compiling against their
    implementations
  Description: When compiling a class against another class
    implementing an interface which is defined in yet another class
    file, such class file (where interface is defined) must be
    available in the class path used by javac during compilation. This
    is a new requirement as of JDK 8 - a failure to do so will result
    in a compilation error.

This commit brings the class file of ItsFacade (its-base) onto the
class path to allow compilation of tests that instantiate
StoryboardItsFacade.
