Fix EZP-22039: ConfigResolver::hasParameter() doesn't check SiteAccess group scope

https://jira.ez.no/browse/EZP-22039

When calling `eZ\Bundle\EzPublishCoreBundle\DependencyInjection\Configuration\ConfigResolver::getParameter()`, parameter is searched in the following scopes:

0. global
0. siteaccess
0. siteaccess groups
0. default

`ConfigResolver::hasParameter()` does not care for siteaccess groups.

This patch fixes this.
