applications: Drop store prefix to generalize

Browse source 
While the Nix store is almost always at `/nix/store`, we shouldn't
assume it to be. Checking only the trailing part of the link is less
exact but removes this bad assumption.

I also added a check for the symlink's contents when overwriting it to
more accurately check whether we own it and should replace it.
