ltlsynt: fix lar.old implementation

Browse source 
* bin/ltlsynt.cc: Make sure to_parity_old() receive a deterministic
automaton, for correctness.   Also call reduce_parity() afterward,
to match what was done in 2.8.7.
* tests/core/ltlsynt.test: Include lar.old in the comparison of all
results to make sure it give the same result as the other 3
algorithms.
