test: simplify test-amend.t to avoid race condition

Insted on relying on sleep, we could simply have the editor do the file change.
This remove the reliance on "sleep" and avoid test failing on heavy load
machine.

To test this, I reverted the code change in 5558e3437872 and the test started
failing again.

This is a graft on stable of 141ceec06b55 which should have targeted for stable.

============================================
Testing obsolescence markers push: Cases C.3
============================================

Mercurial pushes obsolescences markers relevant to the "pushed-set", the set of
all changesets that requested to be "in sync" after the push (even if they are
already on both side).

This test belongs to a series of tests checking such set is properly computed
and applied. This does not tests "obsmarkers" discovery capabilities.

Category C: advanced case
TestCase 3: Pruned changeset on precursors of another pruned one
Variants:
# a: explicite push
# b: bare push
