Never mind, I think I know what's the cause of the problem: I have my
production session of Emacs running on the system ,and it already has the
server started.  So a plain call to server-start fails.

I think you need to modify the tests to ensure the server file is created in
a temporary directory.  And keep in mind that the variable which affects
that is different depending on whether server-use-tcp is or isn't non-nil.
