Progress bar is duplicated when used both as a context manager and as an iterable wrapper

Description

When used both as context manager (e.g. with) and as iterable wrapper, exhausting the iterable and exiting the with scope causes the progress bar to duplicate.

Code

Consider the following example code:

from time import sleep
from progressbar import ProgressBar
from progressbar.widgets import AnimatedMarker, SimpleProgress, GranularBar, Timer

def simple_iterator():
    for i in range(100):
        sleep(0.02)
        yield i

progress = ProgressBar(
    max_value=100,
    redirect_stdout=True,
    redirect_stderr=True,
    widgets=[AnimatedMarker("⡏⠟⠻⢹⣸⣴⣦⣇"), " ",
             SimpleProgress(), " ",
             GranularBar(markers="░▒▓█"), " ",
             Timer()]
)

with progress:
    for i in progress(simple_iterator()):
        pass

I assume finish is invoked twice for some reason, because leaving in either a context manager only or iterable wrapper only, it works as expected.

Bumping because it's still an issue and was not solved.

Sorry about he inactivity, I've seen the issue but I've had very little time.

It's definitely a bug :)

Address issues #212, #295 and lock in #301

Fixed on develop: using a bar as both a context manager and an iterable no longer finishes/draws it twice. Locked by tests/test_with.py::test_context_manager_and_iterable_no_duplicate and the reporter's-exact-widget-set variant test_context_manager_and_iterable_reporter_widgets_no_duplicate added in #326. Closing.
