obsolete: make collapse create less markers
Collapsing A and B into C was registering:
A -> C
B -> C
A -> B
At this point, the last relation brings nothing and is removed for the
sake of simplicity:
A -> C
B -> C
test-evolve.t is slightly modified as one of the relations let stabilize
compute a target outside of the parent revision tree. This is a
stabilize bug, not trivial to fix, so let's tweak the test for now.
