Merge branch 'jc/revert-ref-transaction-hook-changes'
Revert the "deletion of a ref should not trigger transaction events for loose and packed ref backends separately" that regresses the behaviour when a ref is not modified since it was packed. * jc/revert-ref-transaction-hook-changes: RelNotes: revert the description on the reverted topics Revert "fetch: increase test coverage of fetches" Revert "Merge branch 'ps/avoid-unnecessary-hook-invocation-with-packed-refs'"

* Because a deletion of ref would need to remove it from both the

loose ref store and the packed ref store, a delete-ref operation
|

that logically removes one ref may end up invoking ref-transaction

hook twice, which has been corrected.

multi-pack-index" triggered an error, instead of just skipping,

which has been corrected.
