18556 FIX HPE StoreOnce via REST API 4.x: restore authentication after upgrade to 2.5.0

After upgrading from 2.4.0 to 2.5.0, the special agent configured via the rule
_HPE StoreOnce via REST API 4.x_ stopped working against the StoreOnce appliance
and reported a crash with the message `Missing access token parameter`, even
when the configured credentials were correct.

The password configured in the rule was not being resolved from the password
store before being sent to the StoreOnce REST API. The appliance rejected the
login as bad credentials, and the agent crashed while parsing the error
response.

The configured credentials are now forwarded correctly, and the check works
again after the upgrade.
