Revert "Add migration for Image"

 - After discussion with Addy this required `icekit.plugins.images` to
   be in the `INSTALLED_APPS` of the project integrating it for it to be
   picked up correctly. This additional migration is not required.

This reverts commit 28d07102411cbd019bdac97ce6e1251af3bffd35.
