Always raise an error when importing from django.contrib.gis

[benjaoming]

Summary

This is an attempt to address the issue in iiab/iiab#1382

There are version strings of libgeos system libraries that seem to make the loading crash.

TODO

• Has documentation been written/updated?
• Have you written release notes for the upcoming release?

Reviewer guidance

Let's assume that our tests would break, since this is about load-time issues.. not request/response related.
