Alexandre Duret-Lutz 2a38328a5c replace bdd_satoneset(x,y,bddtrue) loops by minterms_of(x,y) 
Because the loops iterate in the opposite order, multiple
test cases need to be adjusted.

* spot/taalgos/tgba2ta.cc, spot/twaalgos/alternation.cc,
spot/twaalgos/dualize.cc, spot/twaalgos/ltl2tgba_fm.cc,
spot/twaalgos/simulation.cc, spot/twaalgos/stutter.cc,
spot/twaalgos/toweak.cc: Replace loops based on
bdd_satonest(x,y,bddtrue) by loops based on minterms_of(x,y).
* tests/core/degenscc.test, tests/core/dualize.test,
tests/core/genltl.test, tests/core/readsave.test,
tests/python/alternation.ipynb, tests/python/automata.ipynb,
tests/python/decompose.ipynb, tests/python/decompose_scc.py,
tests/python/dualize.py, tests/python/sccinfo.py,
tests/python/simstate.py, tests/python/testingaut.ipynb,
tests/python/word.ipynb: Adjust expected test cases.  The
only regression is in genltl.test, but the worsened case
should eventually be fixed as discussed in issue #425 anyway.
