SMT backend: better handling of solver returning unknown #46

When the SMT solver returns unknown, GRASShopper crashes with

Fatal error: exception SmtLibSolver.SmtLib_error(_, "SmtLib: \"line 3086 column 10: model is not available")

I guess there should be a more graceful exit.

To reproduce (on the actris branch):

./grasshopper.native tests/spl/actris/list.spl -v -procedure thread1 -noinst

-noinst triggers the unknown.
