Subject: [PATCH] Fix AutomationListPropertyTest

These tests use reference files that were generated with a particular
value for superclock_ticks_per_second. The default for that has changed
since the last time the reference files were updated though, causing
tests to fail. Rather than updating the reference files for the new
default value, this makes the test not depend on the default value by
hardcoding the value that was used to generate the reference files.
