dotnet pack - version suffix missing from ProjectReference

[natemcmaster]

Follow up to #3953

Repro
ProjectA has project reference to ProjectB.
ProjectB contains <VersionPrefix>3.0.0</VersionPrefix>
dotnet pack ProjectA.csproj --version-suffix build001

Expected
ProjectA.nupkg has dependency on ProjectB 3.0.0-build001

Actual
ProjectA.nupkg has dependency on ProjectB 3.0.0

Details
Using 4.0.0-rc3
Worked in project.json, doesn't work here.
Workaround: msbuild "/t:Restore;Pack" /p:VersionSuffix=build001". Set VersionSuffix property on all projects during restore, not pack.

moving to 4.0 RTM for visibility

likely by design, but will take more time to talk it through post-rtm. easy workaround in initial post.
