Dependency resolution does not work for VSTS feed #1798

Description

I have a private package A in my VSTS feed that depends on a package B from the nuget.org feed. When I paket install, A is resolved and downloaded, but A's dependency on B is not resolved (and B is not downloaded). By comparision, when I source a local folder feed containing A, B is successfully resolved and downloaded.

Repro steps

1. Create a new feed in a VSTS project.
2. For private package A depending on nuget.org package B, push A to the VSTS feed.
3. Add the VSTS feed and package A to paket.dependencies, e.g.:

   • c:\path\to\project\paket.dependencies:

     source https://www.nuget.org/api/v2
     source https://myproject.pkgs.visualstudio.com/_packaging/myfeed/nuget/v2
     
     nuget A
     

4. paket install

Expected behavior

Paket version 3.4.0.0
Resolving packages for group Main:
 - A 0.1.0.36
 - B 1.2.0
Locked version resolution written to c:\path\to\project\paket.lock
2 seconds - ready.

Actual behavior

Paket version 3.4.0.0
Resolving packages for group Main:
 - A 0.1.0.36
Locked version resolution written to c:\path\to\project\paket.lock
4 seconds - ready.

Known workarounds

None.
