Remove some non-determinism in random_graph()

Browse source 
* src/tgbaalgos/randomgraph.cc (random_graph): Revert the part of
the patch from 2007-02-06 which silently replaced the use of state
index by state pointers.  Storing states pointer in this map cause
some non-determinism because of the memory layout.  It was almost
impossible to reproduce bugs found by tests based on randtgba.
