Drop replacing lines from the table when they are exact replacements

Exclude replacing lines from the transaction table output when replacing a single package with the same name.

For #326.

I understand the motivation for this change - fewer rows in the table.
The problem is that useful information is being removed, not just duplicated as stated in the linked issue.

For example, I check from which version to which version the change is happening before approving the upgrade.
Occasionally it happens that a package is replaced by a package with a different architecture, an arch package for noarch and vice versa. Or a package from a different repository.

I understand that not everyone checks what is happening in the system during an upgrade. But I do use this information and it is one of the reasons for me why dnf5 is better than dnf.

I guess we'll have to figure out the "verbosity" of the output somehow, since everyone has different preferences. This PR will satisfy users who want a shorter output at the expense of information (or who have super memory and know exactly what versions and from where they have installed and thus don't need to display it). But it will annoy those who are interested in details. Especially when I manage several different computers I am interested in the exact state of the upgraded computer when upgrading.

There is an intent to have the verbosity configurable with a default level "not detailed". The verbose mode should be implemented by the #1518 after the discussion in #1191.

There isn't a consensus within the team on this approach. Let's wait until things settle around the verbose mode, and then we can decide. We can eventually merge it together when the verbose option is ready.
