doing cabal install --program-suffix=blah produces a confusing message

[ulysses4ever]

Describe the bug

On the second run of the command you expect a failure because the target already exists. But the issue is that the "already exists" message cites a path without the suffix!

To Reproduce

[nix-shell:~]$ cabal --version
cabal-install version 3.10.3.0
compiled using version 3.10.3.0 of the Cabal library 

[nix-shell:~]$ cabal install hello --program-suffix=-new-5
Resolving dependencies...
Build profile: -w ghc-9.6.5 -O1
In order, the following will be built (use -v for more details):
 - hello-1.0.0.2 (exe:hello) (requires build)
Starting     hello-1.0.0.2 (all, legacy fallback)
Building     hello-1.0.0.2 (all, legacy fallback)
Installing   hello-1.0.0.2 (all, legacy fallback)
Completed    hello-1.0.0.2 (all, legacy fallback)
Symlinking 'hello' to '/home/artem/.local/bin/hello-new-5'

[nix-shell:~]$ cabal install hello --program-suffix=-new-5
Resolving dependencies...
Symlinking 'hello' to '/home/artem/.local/bin/hello-new-5'
Error: cabal: Path '/home/artem/.local/bin/hello' already exists. Use
--overwrite-policy=always to overwrite.

[nix-shell:~]$ ls /home/artem/.local/bin/hello
ls: cannot access '/home/artem/.local/bin/hello': No such file or directory

Expected behavior
The error message should cite the path with the suffix. The non-suffixed path may not even exist at all, as shown above.
