Issue Summary

It is possible to create multiple internal tags with the same name, via minor unintended abuse of the Admin API. These tags get a -2 appended to them, for example hash-firsttag if accidentally duplicated becomes hash-firsttag-2 (and then hash-firsttag-2-2 if one makes the same API error repeatedly).

Visiting /ghost/#/tags/ shows only the original hash-firsttag tag, with the posts that have that tag listed. It does not display the additional -2 and -2-2 versions of the tag, making it difficult to see the problem and delete the extra tags. Given that themes use internal tags for a variety of unexpected purposes, this can cause breakages in weird places.
