template: add successors template
The successors templates display the closest visible successors of each
changeset, we may have gap, like in this case:
A -> B -> C -> D
If we display A, C and D but not B, we can't display than B is the closest
successor of A because it's not displayed. We display C as the closest
successor of A instead.
Test that evolve related algorithms don't crash on obs markers cycles
