Build Identifier: 

if repo B is based on repo A which contains package C, then linking to B:C
(without C being directly available in B) produces no UI elements to show
(un)expanded sources in the web UI, neither is the link shown as such ("links
to ...")

example:
https://build.opensuse.org/package/show/KDE:Extra/PackageKit
https://build.opensuse.org/package/show/KDE:Extra/PackageKit?expand=0
https://build.opensuse.org/package/show/KDE:Extra/PackageKit?expand=1

Reproducible: Always

Steps to Reproduce:
1. create link to a package in openSUSE:13.2:Update which is only available in
openSUSE:13.2
2. browse to that link
Actual Results:  
the link exists but is not shown as such

Expected Results:  
same UI as if the package was linked to openSUSE:13.2 directly
