identical names but different paths properly

  HTTP Cookie: header _needs_ to be sorted on the path length in the cases
  where two cookies using the same name are set more than once using
  (overlapping) paths. Realizing this, identically named cookies must be
  sorted correctly. But detecting only identically named cookies and take care
  of them individually is harder than just to blindly and unconditionally sort
  all cookies based on their path lengths. All major browsers also already do
  this, so this makes our behavior one step closer to them in the cookie area.

  Test case 8 was the only one that broke due to this change and I updated it
  accordingly.
