Subject: Dumping unsat cores after check-sat-assuming/QUERY (#5724)

Previously we were not printing unsat cores when passing the option to dump them if we used the check-sat-assuming command or the QUERY command. This commit fixes this.

It also kills the redundant dump-synth option, as it simplifies a bit what is going on in the command executor.
