Start delay of 16s in test discover and execute, because of http request timeout

[dmarzo]

I have this sequence:
00000 devenv.exe, TestRunRequest:SendTestRunMessage: Starting.
00010 Informational: Loading tests from ...
00020 Timeout http request (because of firewall rule, without network connection have no delay)
GET /msdownload/update/v3/static/trustedr/en/disallowedcertstl.cab?2472bccbdab4f384 HTTP/1.1
Host: ctldl.windowsupdate.com
16.000 TestRunRequest:SendTestRunMessage: Completed

I think the problem is at NUnit.VisualStudio.TestAdapter.CleanUpRegisteredChannels() and
XAPPDMN Channel, but I have no idea of how to dig into problem or attach a debuger.

VSNunit Adapter 2.0.0.0

A workaround its disable this validation behavior by setting a grouppolicy for certification.
