obsolete: fix relevant-obsmarkers computation on pruned changeset

The markers pruning a node was not directly considered relevant for the pruned
node, only to its parents.

This went unnoticed during obsmarkers exchange because all
ancestors of the pruned node would be included in the computation.
This still affects obsmarkers exchange a bit since "inline" prune markers would
be ignored (see second test case). This went unnoticed, because in such case,
we always push another obsolescence markers for that node.

We add explicit tests covering this case.

(The set of relevant changeset is use in the obsmarkers discovery protocol used
in the evolve experimental extension, the impact will be handled on the
extension side).

Test safety for inconsistent rebase state, which may be created (and
