Editing an image in media editor and triggering save does not save the image to its jcr node.

Steps to reproduce:

• Edit an image either the detault sub-app of the DAM app or the personas app. E.g. rotate it to the right.
• Save the changes in the image editor. Observe the changed preview in the details sub app. Save the changes in the detail sub app.
• The preview in the action bar does still show the old image. Opening the detail sub-app for the same item also shows the old image.

Inspecting the code I don't think this is specific to DamUploadField, thus reporting against ui.
