Fix windows service.status
Fix windows service.status

Just looking for "PENDING" and considering the status as running is not
correct, because there is a STOP_PENDING and a START_PENDING.

Also fixed a possible race condition in stopping/starting a service,
where the service could still be in STOP_PENDING when salt attempts to
start it.
