[nem-en] N.C.Hashtable behavior when the key is not found

[Kamil Skalski]

I'm suprised. I also thought it will throw exception now, as we
switched its implementation to SCG.Dictionary. I guess we should
change...

And one more thing, did you run 'svn blame'.., I'm a bit afraid it
will point on me though ;)
