Makes QSmoothedAnimation respect zero duration.

In automated GUI test scenarios it often desired not to wait for animations
before verifying a result, so setting the duration to zero should accomplish
this, before this patch; if duration was set to zero QSmoothedAnimation
would treat it as if duration was not set, and used velocity to calculate
animation speed.
