MINOR: check: Always increment check health counter on CONPASS

Regarding the health counter, a check finished with the CONDPASS result is
now the same than with the PASSED result: The health counter is always
incemented. Before, it was only performed is the health counter was not 0.

There is no change for the disable-on-404 option because it is only
evaluated for running or stopping servers. So with an health check counter
greater than 0. But it will make possible to handle (STOPPED -> STOPPING)
transition for servers.
