[PATCH v2 2/8] reftable/stack: do not auto-compact twice in `reftable_stack_add()`

In-Reply-To: <cover.1703743174.git.ps@pks.im>

In 5c086453ff (reftable/stack: perform auto-compaction with transactional interface, 2023-12-11), we fixed a bug where the transactional interface to add changes to a reftable stack did not perform auto-compaction by calling `reftable_stack_auto_compact()` in `reftable_stack_addition_commit()`. While correct, this change may now cause us to perform auto-compaction twice in the non-transactional interface `reftable_stack_add()`:

  - It performs auto-compaction by itself.

  - It now transitively performs auto-compaction via the transactional
    interface.

Remove the first instance so that we only end up doing auto-compaction once.
