tags: automatically fix incorrect tag counts during maintenance.

* Automatically fix all tags with incorrect counts during daily
  maintenance (previously only tags with negative counts were fixed).
* Log fixed tags to NewRelic.
* Remove the ability to manually fix tag counts with the "Fix" button on
  the /tags listing. This is no longer necessary now that tags are
  fixed automatically.
