  - conflicting requests

Expected results:
packages are swapped

Additional info:
* when dnf5-plugins is not installed 'dnf5 swap dnf5 zsh' swaps the packages without any problems
* 'dnf5 remove dnf5' works OK even when dnf5-plugins is installed

Actually here the behavior is exactly the same as with dnf4.

What you need to do is add `--allowerasing` cmdline option (for both dnf4 and dnf5). But it would be nice if dnf5 could print a hint to the user.
