tests: remove all remaining usage of experimental.bundle2-exp

The only remaining usage of the experimental config were enforcing bundle2 on.
These are very old remains of when bundle2 was off by default. This was also
useful to highlight the fact that this was a bundle2 run and that a bundle1 one
was nearby. However, we want a future developer working on bundle3 to notice
possible output/behavior change on these tests and take them in account.  So we
do not enforce bundle2 for these runs. We leave a comment around to make sure
dev still notice the bundle1 version.
