roslyn: Project.AssemblyName does not accurately report assembly name.

The following code suddently started appending “.csproj” onto assembly names which seems wrong.

private IReadOnlyList<string> GetTargetAssemblies()
{
    List<string> result = new List<string>();

    foreach (Microsoft.CodeAnalysis.Project project in this.workspace.CurrentSolution.Projects)
    {
        // .Net Core projects can have ".csproj" attached sometimes.
        result.Add(project.AssemblyName.Replace(".csproj", string.Empty));
    }

    return result.AsReadOnly();
}

It is important to keep apis reporting data in a consistent format. if it doesn’t it requires rolling out extension updates for no useful reason.

Here is the csproj that causes the assembly name to be wrong:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netstandard2.0</TargetFramework>
    <AssemblyName>Microsoft.Exchange.Diagnostics</AssemblyName>
  </PropertyGroup>
</Project>

Note: I must have <AssemblyName> in this new format project because there is no other way (known? supported?) to find the target assembly programmatically between old and new format csproj files.
