shortlog: make trailer insertion a noop when appropriate
When there are no trailers to insert, it is natural that insert_records_from_trailers() should return without having done any work. But instead we guard this call unnecessarily by first checking whether `log->groups` has the `SHORTLOG_GROUP_TRAILER` bit set. Prepare to match a similar pattern in the future where a function which inserts records of a certain type does no work when no specifiers matching that type are given.
