tests: add more verification of output to divergence tests
It's not obvious what the obsmarkers should look like in these tests
and adding them highlights a bug that happens when commit we create to
resolve the divergence doesn't get created because it would be
empty. I also added a few graphlog calls to check that the
divergence-resolution commit is in the right place (has right
parentage).
