Sharesheet - Photos -> Sharesheet in work profile crashes

The issue stems from adding the incorrect userid when first entering
the sharesheet. The flow from Photos sendkit directly to the work
profile sharesheet was setting the incorrect userid on the content
uris. Move this logic to the correct location.
