util.prosodyctl.shell: Close state on exit to fix saving shell history This ensures a last round of garbage collection and finalizers, which should include flushing the readline history file. Test procedure: ``` $ ./prosodyctl shell prosody> s2s:show() -- any command that is not the last in history ... output prosody> bye $ ./prosodyctl shell prosody> ^P ``` After this, the shell prompt should contain the last command from before the "bye". Before this patch, recent history is gone most of the time.
