unit test syntax/Test3

[gerdstolpmann]

Fails with:

==== Test3
running osh Test3
fact(10) = 3628800 [SUCCESS]
*** omake error:
   File /home/gerd/pub/omake/test/syntax/Test3: line 8, characters 4-12
   Array value where string expected:
      Use the $(string ...) function if you really want to do this
      The array has length 3:
         [0] = 11 : Int
         [1] = 21 : Int
         [2] = 31 : Int

Apparently, the test code assumes that we can compare lists directly, though we actually cannot.

A couple of other tests also fail because of this.

Fix in #47
