tgba_digraph: Fix handling of initial state.

Browse source 
* src/tgba/tgbagraph.hh: Store the number of the initial state, not a
pointer to it, because if the state vector is reallocated due to some
later calls to new_state(), this pointer will be invalid.
* src/graphtest/tgbagraph.cc, src/graphtest/tgbagraph.test: Test
for this.
