Load balanced URIs get mangled in DefaultLinkResolver.Resolve

[ryanrousseau]

When using a load balanced URI with OctopusClient, the response.Location from DispacthRequest can be a fully qualified URI. This is passed to DefaultLinkResolver which sees that it does not begin with a / and adds a / to the beginning of the fully qualified URI.

This can be reproduced by using octo.exe create-release using a load balanced URI.
