It was only used on OS X and couldn't be used by the FinderSync extension since that one runs in a sandbox. So use the same system to load images in the legacy extension by shipping them in the extension bundle instead of the owncloud.app bundle. This is also given that the legacy extension needs padded icons while the FinderSync one needs unpadded icons.
