Invalid links section for get access token

[Steve Martinelli]

Currently, when getting a single access token:

{
    u'access_token': {
        u'authorizing_user_id': u'53965ee69aa145128a1e91f424745cfe',
        u'links': {
            u'self': u'http: //localhost: 5000/v3/access_tokens/aecec537d2634285a506299cc49a9b32',
            u'roles': u'http: //localhost: 5000/v3/users/53965ee69aa145128a1e91f424745cfe/OS-OAUTH1/access_tokens/aecec537d2634285a506299cc49a9b32/roles'
        },
        u'expires_at': u'2014-02-13T20: 05: 53.011663Z',
        u'consumer_id': u'63e7c900ff4047148bf748999602de33',
        u'project_id': u'777527ead8084667890a362512c9a2d1',
        u'id': u'aecec537d2634285a506299cc49a9b32'
    }
}

Note that the self portion should have: /users/$user_id/OS-OAUTH1

The link for a listing seems to be fine:
{
    u'access_tokens': [
        {
            u'authorizing_user_id': u'c5acd8824d804550a55da5ca3a33dfee',
            u'links': {
                u'self': u'http: //localhost: 5000/v3/access_tokens/5d0084cd834c4ccba51a2349448f9dc7',
                u'roles': u'http: //localhost: 5000/v3/users/c5acd8824d804550a55da5ca3a33dfee/OS-OAUTH1/access_tokens/5d0084cd834c4ccba51a2349448f9dc7/roles'
            },
            u'expires_at': u'2014-02-13T20: 07: 44.097317Z',
            u'consumer_id': u'c57ea70185a240b8bb09b993e9c5d07c',
            u'project_id': u'e75b5f3d9ca8432c9527609d7aea7e01',
            u'id': u'5d0084cd834c4ccba51a2349448f9dc7'
        }
    ],
    u'links': {
        u'self': u'http: //localhost: 5000/v3/users/c5acd8824d804550a55da5ca3a33dfee/OS-OAUTH1/access_tokens',
        u'next': None,
        u'previous': None
    }
}

    Fix invalid self link in get access token

    When getting a single access token, the `self` link didn't contain user section.
    This commit fixes the url by overriding the method that generates the self
    referential links and adds corresponding test.
