build checks exception

[SimaTian]

Issue Description

While benchmarking buildchecks on orchardCore, an exception was thrown.

Steps to Reproduce

While benchmarking,
I was running the MSBuild with following parameters:

foreach ($number in 1..20) {
	D:\bld\artifacts\bin\bootstrap\net472\MSBuild\Current\Bin\MSBuild.exe OrchardCore.sln -maxcpucount:10 -tl:true -t:Clean | Out-Null
	pskill msbuild | Out-Null
	(Measure-Command {
		D:\bld\artifacts\bin\bootstrap\net472\MSBuild\Current\Bin\MSBuild.exe OrchardCore.sln -maxcpucount:10 -tl:true -check  -warnAsMessage:"BC0102;BC0105;BC0202"
	}).TotalSeconds | Out-Default
	
	
}

Expected Behavior

Run succeeds without issues.

Actual Behavior

During the scheduled 20 runs, one failed with:

Unhandled Exception: Microsoft.Build.Framework.InternalErrorException: MSB0001: Internal MSBuild Error: ContextID 87025 should have been in the ID-to-project file mapping but wasn't!

Analysis

I have no idea, if I run into the error more than once, I will try to reproduce it with binlogs enabled.
