When saving a description the one edited doesn't appear but the one edited previously instead. This fixes this problem. Technical note: the default description for a new event was the rendering of a template. That template was shared between all the events and overridden each time. The solution was to strip the identity of the template while rendering it making it a constant and preventing it from being shared between events. This could be done by setting rendering_bundle to True in the rendering context (unfortunately, t-ignore is not a legitimate attributes of template tag). Note that the same fix [1] was done on `website_hr_recruitment`.
