Non-duplicate framework dependencies get removed

[Stift]

Description

Framework Dependencies get removed from project files when running paket install. With paket 3.12.0 and later!

Repro steps

We have a package which depends on different framework deps (e.g. System.Configuration, System.IdentityModel, System.Runtime.Serialization, System.Web, System.XML, System.XML.Serialization). Another package has some similar dependencies (System.Configuration, System.IdentityModel, System.ServiceProcess).
When running paket install the references get removed despite the project has no dependencies defined neither the other packages. Somehow all dependencies of dependent packages won't be used.
After some investigation I think the wrong behaviour is, when there is a duplicate framework-dependency, all framework-dependencies get removed. In the case above I would assume that System.ServiceProcess should stay which is not.

The repo attached can be used to replay that.

Expected behavior

Dependencies should stay as they are. Only remove the duplicates

Known workarounds

Use Version 3.11.3 and lower. It seems with the fix of bug #1333 this behaviour was introduced.
