After progressiveStop() is called, the callback method onStop() is called infinite times about smoothprogressbar

Related to #35.

The ActivityThread change the visibility of the decor after onResume() is called, setting it to INVISIBLE, then to VISIBLE. This visibility change will be dispatched through the whole hierarchy, including ProgressBar. When the ProgressBar's onVisibilityChanged(View, int) is called with a visibility = GONE/INVISIBLE, it stops the animation, which will call the SmoothProgressBar.CallBacks#onStop() method.
That is why onStop() will be called just after onStart(). Unfortunately, we set the visibility to GONE in the callback, so the ProgressBar won't be shown :(

Didn't have the time to find a workaround yet. And forgot a bit too TBH.
