[Bug 847976] Use locale for question progress.

The question listing progress bar did not consider any filters,
specifically locale filters. Considering the level of seperation between
different locales in the questions app, this isn't good.

This change is to consider only the current locale when calculating the
percentage the progress bar should be filled.
Re-update django-eadred.
