test/utils: disable Thread's report_on_exception in start_server

Those threads can purposefully raise exceptions when they call 'pend'.
The report_on_exception feature can be safely disabled in this case
since we use assert_join_threads that captures all exceptions raised.

This is necessary to suppress warnings on Ruby 2.5, which enables the
report_on_exception feature by default.
