Retro compatibility on xwiki.store.attachment.recyclebin.hint=file does not work

xwiki.store.attachment.recyclebin.hint=file is deprecated but it's still supposed to work.

Getting

Can't find descriptor for the component with type [interface com.xpn.xwiki.store.AttachmentRecycleBinContentStore] and hint [default]

The workaround is to comment it and instead use the valid configuration: xwiki.store.attachment.recyclebin.content.hint=file.
