sbacc: remove spurious initial state in some output

Browse source 
This fixes #492, based on a report from Jérôme Dubois.

* spot/twaalgos/sbacc.cc: If the initial state is in a rejecting
component, start with an initial state whose colors are unsat_mark.
* tests/core/sbacc.test: Add test case.
* tests/python/pdegen.py: Adjust it.

New in spot 2.10.2.dev (not yet released)
Nothing yet.
Bugs fixed:
- On automata where the absence of color is not rejecting
(e.g. co-Büchi) and where the initial state was in a rejecting
SCC, sbacc() could output a superflous state. (Issue #492)
New in spot 2.10.2 (2021-12-03)
