Fix: relayd not spawned on default-url live session creation

b178f53e9 introduced a regression that causes the lttng client to
not spawn a relay daemon automatically when a live session is
created using the default url parameters.

This fix re-introduces an equivalent check to restore the
previous behaviour.
