REVISION SUMMARY
  Adding a test for fullcopytracing algorithm where both the merging csets
  are dirty, which means no cset is descendant of merging base.
  
  This test shows that for this particular case fullcopytracing algorithm
  worked and found the copies. But there are the cases when the algorithm
  can fail to handle this "both dirty" case and errors.
  
  Next couple of csets will add those test cases when it fails and fix for
  the same.
