simplify_acc: loop over the simplifications

Browse source 
* spot/twaalgos/cleanacc.cc (simplify_acceptance_here): Run the
simplifications in a loop until the condition does not change anymore.
* tests/python/simplacc.py, tests/core/accsimpl.test,
tests/core/remfin.test, tests/python/merge.py,
tests/python/simplacc.py, tests/python/toparity.py: Update expected
results.
* tests/python/automata.ipynb: Update the failing example to a more
interesting one, matching the one in doc/org/autfilt.org.
