Seth Vargo ff95fc5c1e Only append access_token the first time
This fixes GH-6395 by only appending the access_token once. It also fixes a
bug that was never reported. If a user supplied an access_token for a box URL,
Vagrant would silently overwrite it.

After this commit, Vagrant only appends an access_token to the URL if no
value exists at the key.
