When creating image objects through the Public API, image content is placed directly in the legacy images root, for example:

var/<something>/storage/images/1712-1-eng-GB/Chrysanthemum.jpg

After editing the same image object from the administration interface, the image is saved to the correct location:

var/<something>/storage/images/media/images/test/1712-1-eng-GB/test.jpg

Steps to reproduce:

1. Create an image object using the public API, verify that the image content is placed directly under <var_dir>/images
2. Create an image through the admin interface, verify that it's placed in <var_dir>/images/<xxx>/...
3. Edit the image object created in step one, and save it again. Verify that the updated image is saved in the correct location (consistent with the result from step two).
