Tags WebUI count doesn't match API

[pm17788]

Environment

• Python version: 3.5.2
• NetBox version: 2.5.8

Steps to Reproduce

1. Browse to: https://NetBoxURL/extras/tags, see count of tags (ex: 25)
2. Browse to: https://NetBoxURL/api/extras/tags, see count which is an aggregate of all tagged items, rather then the count of distinct tags in NetBox

Expected Behavior

API count of tags should match the WebUI and the API

Observed Behavior

API count of tags doesn't match the WebUI, or the behavior of count variable on other API endpoints.

@jeremystretch: Just tested on 2.5.12, and this appears to still be an issue.
https://netbox-dev/api/extras/tags/ still returns as its top-most thing:

    "count": 4436,
    "next": "https://netbox-dev/api/extras/tags/?limit=150&offset=150",
    "previous": null,
    "results": [

I only have 25 distinct tags (per https://netbox-dev/extras/tags/)
Am I misunderstanding the purpose of the /api/extras/tags endpoint?
