nix profile: suggest removal using entry name

Browse source 
When a file conflict arises during a package install a suggestion is
made to remove the old entry. This was previously done using the
installable URLs of the old entry. These URLs are quite verbose and
often do not equal the URL of the existing entry.

This change uses the recently introduced profile entry name for the
suggestion, resulting in a simpler output.

The improvement is easily seen in the change to the functional test.
