utilities/auto-blog-link-preserver#19: Failure count stat can be higher than link count

In stats output to InfluxDB, the reported failure and duplicate counts can be higher than the reported number of total links seen.

This is as a result of the code-shift around done for #10

Submission is handled separately for URLs referenced within the source RSS feed itself, but the link counter is not incremented:

# Submit the link itself to linkwarden
page_status = submit_to_linkwarden(entry.link, tags)
# TODO: DRY this up
if page_status == 0:
    failure_count += 1
elif page_status == 2:
    duplicate_count += 1    

So any recorded failure or duplication will not be mirrored by a count in the overall total
