evolve: support successors of ancestor of orphan with multiple roots

The previous code checked that the set of successors has a single root.
However, there’s no reason to require that in general.

Example:

o 6
|
o 5
|\
| o 4
| |
o | 3
|/
| * 2
| |
| x 1
|/
o 0

1 is obsoleted by 3, 4 and 6. We are considering the case when 2 gets evolved.

The roots are [3, 4] and the heads are [6]. Before the change, the user was
asked which destination to choose, but there was only one choice (6). After the
change, 6 is chosen as the destination.

Tests the resolution of content divergence: relocation
======================================================

This file intend to cover case where changesets need to be moved to different parents
