Fix extremely rare and extremely weird bug

Browse Source 
Under certain conditions, it was possible to get orderLinks() trigger a
segmentation fault or a SIGBUS; even if all the Link* and Linkapp*
pointers where correct, the compare_links() function would eventually
end up receiving an invalid pointer.

Apparently, the std::sort function *requires* that the assertion
compare_links(a, b) != compare_links(b, a) is always true, which was not
the case previously when a link was compared with itself.
