Do NOT disc_load from ram_copies when master_node is set
Setting master_nodes to a node with ram_copies replica and that node had not loaded the table, could cause it load an empty table, even though (non master) nodes had disc_replicas. This meant that tables where unexpected empty after multiple failures happened. When this happen do not load the table and wait for user to force_load it on some node, preferably with a disk copy.
