[Koha] Logging action_logs when merging records

[Pedro Amorim]

Hey all,

Recently I noticed that no action_logs are created when merging biblio
records together, I was expecting to have in the action_logs all the
actions that were made, but nothing is logged as opposed to a regular edit
or delete, for example.

I was wondered if this is intentional, there's a way to enable it or the
feature is just missing.

Thanks a bunch,

Pedro Amorim
