[BUG] Go client returns an empty result when calling Root.Get()

[HuyPhanNguyen]

Description When calling Root.Get() in the Go client library, the resulting RootResource is blank. This occurs because the RootService is incorrectly calling an endpoint like http://localhost/api/Spaces-1 when it should be calling http://localhost/api.

Steps To Reproduce Provide a detailed list of steps that reproduce the issue.

• Use the Go client library
• Call the Root.Get() function
• Observe that the returned RootResource is empty/blank

Expected Behavior The Root.Get() function should return a properly populated RootResource object with all the expected data from the root API endpoint.
