graph/sharedWithMe: Adjust the driveItem's ID once more

In order to be able to group shares received for the same resource in a single driveItem
the driveItem's ID needs to be unrelated to the underlying shares' ids. We decided to base
it off of the shared resource's id (currently
{sharesstorageproviderid}${sharejailid}!{resourceid of shared item})
