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.5
===============================================

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 5: one side relocated backward and other rebased to parent's successor
Variants:
# a: "local" is relocated backward
# b: "other" is relocated backward

A.5 Relocated backward; Rebased to parent's successor
=====================================================

.. (Divergence reason):
..    local: relocated the changeset backward in the graph
..    other: rebased to the successor of parent
.. Since one side rebased to the successor of parent and other cset relocated backward,
.. the most reasonable behaviour is to set the parent of "backward-relocated" cset
.. as resolution parent of divergence.
