tests/simple: Fix the missing IP test
Update the missing IP test to wait until restarts are complete.
Otherwise a service restart can collide with the following monitor
event and cause chaos.
Also, do not disable 10.interface until it matters. Disabling it too
early can cause even more chaos if something goes wrong with the
monitor step.
