master/testAutostart: Make sure to verify cluster actually reaches RUNNING state

Upon #storage reaching #autostart, with autostart being on, by
definition if recovery / verification phases can be completed, the
cluster should change its state to RUNNING.

The corresponding test (introduced in 58774fb6 "master: new option to
automatically start a new cluster") was not checking that.
