[2/2] Fix sharing to another profile where an app has multiple targets

Complete the change in ag/19657256 to also apply in SelectableTargetInfo.
That would ensure that in all cases of cross-profile targets the URIs
are fixed to include the user-id prefix.

Test: manually share image from work Photos app to personal WhatsApp's
frequent contact target.
