Paket tries to resolve wrong dependecy group

Description

When trying to install the nuget package "Google.Apis.AdSense.v1_4" on .Net 4.5, Paket fails with unmet dependencies. This seems to be due to a very unusual targetFramework definition:

      <group targetFramework=".NETStandard1.3">
        <dependency id="Google.Apis" version="1.16.0" />
        <dependency id="Google.Apis.Auth" version="1.16.0" />
      </group>
      <group targetFramework=".NETPortable0.0-Profile259">
        <dependency id="Google.Apis" version="1.16.0" />
        <dependency id="Google.Apis.Auth" version="1.16.0" />
      </group>
      <group targetFramework=".NETPortable0.0-Profile328">
        <dependency id="Google.Apis" version="[1.10.0]" />
        <dependency id="Google.Apis.Auth" version="[1.10.0]" />
      </group>

The dependencies from ".NETPortable0.0-Profile328" are used, but they are invalid. Instead, the dependencies from ".NETPortable0.0-Profile259" are the desired ones.

Repro steps

1. Check out https://github.com/pdfforge/paket-bugreport
2. Call paket install

Expected behavior

Actually, I do not know if this is a correct way to define the dependencies, but the desired behaviour would be to reference Google.Apis 1.16

Known workarounds

Right now, I don't know of any. I will post an issue for that on the Google project itself to check if the targetFramework definition is made properly.

Start by checking out the linked pdfforge/paket-bugreport repository and running paket install to reproduce the unmet dependency error. Trace how Paket selects between the .NETPortable0.0-Profile259 and Profile328 groups; done means the install resolves Google.Apis and Google.Apis.Auth at version 1.16.0 for this case.
