build binary test artifacts (#477)

* build core repor's binary test artifacts before running tests.

* fix test case that depended on the current decade (nice catch by @mdeuser)

* ignore test that requires a specific Java jar. 
  It was broken by removal of binary artifacts from core repository.
  Since the jar was not actually used anywhere else, it is not built
  by core's test:buildArtifacts.
