Fix #691: setting \tempo without duration shouldn't print a duration

We can turn off the printing of (dur=count) by simply unsetting the count and duration properties (they are unset in the beginning, so I don't think this will break anything, but then, I'm not totally sure...)
Also added a show regtest for this case.
