test-merge-tools.t: add 'hg resolve --list' output to tests

In upcoming patches we're going to be making some improvements to the ':prompt'
merge tool, and one of them is recovering appropriately from exceptions. It is
important in such cases to make sure that the merge state is written out
properly.

I went through the output and verified that it all makes sense.
