2nd Level Dependency With Mismatched Version Missing

## Setup

ProjectA (Class Library) - Direct Nuget dependency on Lib1 which has indirect nuget dependency on Lib2
ProjectB (Console Application) - Project reference to ProjectA

Lib1 nuget states version >= 1.0.0
Lib2 is version 1.1.0

## The Observed Result

ProjectA compiles fine & has both Lib1 and Lib2 in the bin.
ProjectB compiles fine, has ProjectA.dll and Lib1 in the bin.
ProjectB is missing Lib2.
ProjectB (Console Application) has a runtime error since Lib2 is not present

## Initial Findings

MSBuild output states that it will not take Lib2 (when compiling ProjectB) as there is a mismatch in the "FusionName" which appears to be the assembly plus the version and key.

## Looking at MSBuild Code

This may be (i'm tried debugging, but its tough) related to assembly unification.
For some reason ProjectB requires a specific version whereas ProjectA does not.
