[Console][ProgressHelper] Fix ProgressHelper redraw when redrawFreq is greater than 1

When using a ProgressHelper object with redrawFreq > 1, there are situation where redraw may never occur.
E.g.
 - redrawFreq = 2
 - setContent = 1
 - advance(2)
... the redraw event is detected by 0 == current % redrawFreq.

I've tested the patch against phpunit and my local environment.

Maybe, a new test can be implemented to avoid the previous example, but I'm not familiar with mock object... :)
