evolve: abort when trying to move a node on top of itself

This provides a clearer error message when evolve misstakenly tries
to move a changeset on top of itself. Before we got an abort with a
cryptic message about trying to rebase a merge changeset.

A proper fix to make sure that evolve never tries to move a node on
top of itself will come in later patches.

Initial setup

  $ . $TESTDIR/_exc-util.sh


=== B.5 Push of a children of changeset which successors is pruned ===

.. This case Mirror A.4, with pruned changeset successors.
..
.. {{{
..   B ◔
..     |
..   A⇠ø⇠⊗ A'
..     |/
..     ● O
.. }}}
..
.. Marker exist from:
..
..  * `Aø⇠○ A'`
..  * chain from A
..  * `A'`
..
.. Command run:
..
..  * hg push -r B
..
.. Expected exchange:
..
..  * `Aø⇠○ A'`
..  * chain from A
..  * `A'`
..
.. Extra Note:
..
..   I'm not totally happy about this case and I believe some more complicated
..   graph can result in behavior wuite confusing for the user (if some tool create
..   prune maker in a the middle of a valid chain)
