tmp_proj doesn't get evaluation Properties+Items folders

[AArnott]

In our vs-platform repo when I run MSBuild vseditor.csproj /bl and open the MSBuild.binlog file, the properties and items folders under the *.tmp_proj project are missing (but present for other projects).
See here:

But when I use the older command syntax for logging ("C:\Program Files (x86)\Microsoft Visual Studio\pubrelease\MSBuild\15.0\Bin\MSBuild.exe" D:\git\VS-Platform\src\Editor\Consolidated\VSEditor\VSEditor.csproj /t:Rebuild /v:diag /nologo /noconlog /logger:StructuredLogger,"C:\Users\andarno\AppData\Local\MSBuildStructuredLogViewer\app-1.2.5\StructuredLogger.dll";"C:\Users\andarno\AppData\Local\Temp\MSBuildStructuredLog-16600.buildlog", the properties and items folder do show up.

I've seen this before but could never track it down. My hypothesis is that this is something in MSBuild, under some circumstances this is null:

MSBuildStructuredLog/src/StructuredLogger/BinaryLogger/BuildEventArgsWriter.cs

Line 225 in 1b21660

WriteProperties(e.Properties);

Probably related to dotnet/msbuild#3616

This should be fixed by dotnet/msbuild#6287

Fixed and should appear in 16.10.
