Integration link queue multiplication

Problem/Motivation

Where would the log be generated? Is it in \Drupal\acquia_dam\IntegrationLinkRegister::removeIntegrationLink where we log if there are no integration links found?

if (empty($integration_links)) {
  $this->damLoggerChannel->warning(sprintf(
    'There are no integration links associated with entity: %s in local storage',
    $entity_uuid,
  ));
}

If that's the case, I think it's fine that we just remove the logs and exit out, assuming it was double queued somehow.
I see it's also in \Drupal\acquia_dam\IntegrationLinkRegister::removeTrackings.

Steps to reproduce

• Create node and import a DAM asset
• Run cron -> integration links are created (one for media and one for the node)
• Delete media -> 2 queue items are created to delete integration links
• DO NOT run cron but deleted the node. -> new queue item created to delete integration link (node)

At this point there are 2 queue items for the same task which is not necessary.

Proposed resolution

Instead of trying to work around Drupal's lack of handling for dupe queued items I think it's fine to just remove the logs and let the possible duplicates get processed. They'll just exit silently if they've already been handled.
