[RFC PATCH v2 1/2] t3303/t9301: make `notes` tests less brittle

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

From: Eric Sunshine <sunshine@sunshineco.com>

These tests care about whether intended notes-related functionality
occurred, but they check for the expected result in a brittle way by
consulting the default output of `git log` which is intended for human,
not machine, consumption. Make the tests more robust by requesting the
desired information in a stable machine-consumable format.
