improve translation of ms-phi-h=2..3

Browse source 
* spot/twaalgos/gfguarantee.cc: Rework the history computation to keep
an overapproximation of the history, and a longer one.  Also replay
the history even if there is no initial trivial SCC.  This helps with
translating FG(!a|XXXb) where we need to keep the history of a, but we
were previously unable to do so because some state had both "a" and
"ab" as input.
* spot/twaalgos/translate.cc: Optimize the product of suspendable
automata by removing useless trivial SCCs.
* tests/core/genltl.test, tests/core/satmin.test, NEWS: Adjust
expected results.
