Increase Timeout in WaitForRefreshAndCloseIT (elastic#76078) (elastic#76082)

The test cluster took slightly more than 10s to apply the cluster state for the mapping update
randomly which failed the run in elastic#75941. This only ever failed once but since there's no real harm in doing so
increasing the timeout to 30s here like we did in other similar spots.

closes elastic#75941
