ltlsynt: fix syntax error handling

Browse source 
Fixes #477.

* bin/common_finput.cc (job_processor::process_string): Fix return
value.
* bin/ltlsynt.cc: Fix handling of syntax errors.  While we are here,
make sure game_info is destroyed before Spot's globals.
* tests/core/ltlsynt.test: Add a test case.
