Get operations on tags return NotFoundError

[ats3v]

I get this error pretty consistently both when getting all tags or a single one:

send: 'GET /v2/tags?per_page=200 HTTP/1.1\r\nHost: api.digitalocean.com\r\nConnection: keep-alive\r\nAccept-Encoding: gzip, deflate\r\nAccept: */*\r\nUser-Agent: python-requests/2.14.2\r\nAuthorization: Bearer <token>\r\n\r\n'

Using CURL and following the example in https://developers.digitalocean.com/documentation/v2/#retrieve-a-tag works just fine.

After talking to the DO support, they suspect that not passing Content-Type: application/json in the headers is the problem. This lib passes it only for non get requests.

If you want to try and find a fix for this you are more than welcome. A simple change that ensures the Content Type header might work 🤷‍♂

I've only done the unit tests and it passes. It needs some more testing.
