Johannes Sixt 984f78d278 rebase topology tests: fix commit names on case-insensitive file systems
The recently introduced tests used uppercase letters to denote
cherry-picks of commits having the corresponding lowercase letter names.
The helper functions also set up tags with the names of the commits.

But this constellation fails on case-insensitive file systems because
there cannot be distinct tags with names that differ only in case.

Use a less subtle convention for the names of cherry-picked commits.
