Versions panel: Assume less about the signature of apps' `get_version()` (was: Running with wagtailmenus)

Hi,

I'm having an issue using django-debug-toolbar with wagtailmenus : a menu app for wagtail.

jazzband/wagtailmenus#115

Any idea ?

Yeah, the code might be made more defensive in this area, and not crash and burn just because the signature of get_version differs between apps.

This should be an easy fix for a first time contributor.
