- add test for serialized fn containing a call to println

This test fails for me on scala 2.10.0 with:

    [error] x Serialize objects with Fns should
    [info]   + fn calling
    [info]   + roundtrip the object
    [info]   + Handle traits with abstract vals/def
    [info]   + KryoInjection handle an example with closure to function
    [error]   x handle a closure to println
