Amir Sarabadani d9370003fb maintenance: Introduce getReplicaDB() and getPrimaryDB()
And start using them instead of wfGetDB(), LB/LBF connection methods or
worse, $this->getDB().

$this->getDB() reuses the database object regardless of whether you're
calling a replica or primary, leading to returning a replica on a
primary and other way around.
