Use test-server on CI (#2034)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Vary what SpawnType is used, if one isn't explicitly set.

* Terminate on linux if exec fails.

* Use a more sophisticated sleeping mechanism.

* Attempt to make CI tests to work on aarch64 debug.
Small fixes.
