run-tests: resume raising an exception when a server fails to start

Prior to 93228b2a1fc0, this exception was raised before the diff could be
printed.  By raising the exception after printing the diff, the location of the
failure can be identified, but it is also easier to locate test runs where this
occurs.  The test bot maintains a list of failed tests, separate from the wall
of diff output.
