Progressbar does not update

[frsche]

Description

update() does not update the progressbar when no Timer() (or ETA() etc.) widget is used.

Code

import progressbar, time
widgets = [progressbar.Percentage(), progressbar.Bar()]
bar = progressbar.ProgressBar(widgets=widgets, max_value=100).start()
for i in range(100):
    time.sleep(0.5)
    bar.update(i)

Always shows

N/A%|                                                                            |

If i use bar.update(i, force=True) it works as expected. If i change the second line to

widgets = [progressbar.Percentage(), progressbar.Bar(), progressbar.Timer()]

it's also works as expected.

It appears that this was broken at some point and slipped through the tests because they mostly check timed variants. I've added an extra test and fixed the bug :)

I'll release a new version once travis is done
