Title: Fixed transoffset example from failing.

This issue came about because the polar axes which had already been created via ```plt.subplot``` wasn't getting picked up with a simple ```plt.gca(projection='polar')``` due to different gridspecs. I have removed the use of the gridspec in the key comparison of gca, and added a few tests which cover these changes.

Fixes #1084.
