tests: update old changeset hashes in test-tutorial.t

They actually should've been updated in 32ed5b6fadd3, but better late than
never.

Unfortunately, these messages are not tied directly to any command output, so
the issue with using nonexistent hashes was not immediately obvious after
running this test.

===============================================
Testing content-divergence resolution: Case A.2
===============================================

Independent rewrites of same changeset can lead to content-divergence. In most
common cases, it can occur when multiple users rewrite the same changeset
independently and push it.

This test belongs to a series of tests checking the resolution of content-divergent
changesets.

Category A: no parents are obsolete
Testcase 2: no conflict: both sides amended content changes (non-conflicting changes in same file)

A.2 both sides amended content changes
======================================

.. (Divergence reason):
..    local: amended some content changes in same file as "other" but non-conflicting
..    other: amended some content changes in same file as "local" but non-conflicting
.. Where we show that since both side amended some content changes without any relocation,
.. the most reasonable behaviour is to simply perform 3-way merge.
..
.. (local):
..
..   A ø⇠○ A'
..     |/
..     ● O
..
.. (other):
..
..   A ø⇠○ A''
..     |/
..     ● O

.. (Resolution):
