Column names for packages are always printed

[kontura]

In the transaction table the column names for packages are always printed even if no packages are changed. For example:

$ sudo dnf5 group install vlc --no-packages
Updating and loading repositories:
Repositories loaded.
Package          Arch   Version Repository      Size
Installing groups:
 VideoLAN Client

Transaction Summary:

After this operation 0 B will be used (install 0 B, remove 0 B).

The line Package Arch Version Repository Size seems strange. I see dnf4 also does this.
