core: Fix wrong db initialization

Before this patch, when pool got empty during its initialization, and
tried to write log about it into AuditLog, NPE was thrown, because
DbFacade wasn't initialized yet. Such NPE brought several singletons
down blocking ear from being deployed.

The reason for that is probably that there's a code using
org.ovirt.engine.core.dal.dbbroker.DbFacade#getInstance
which gets initialized only after DbFacade bean is properly constructed.
Injecting DbFacade into MacPoolPerCluster seems to fix the issue, since
DbFacade gets initialized during inject and thus getInstance will
return correct non-null instance when called.
