Subject: [PATCH] Reset NodeRegion when a node gets mounted to a View

Summary: Small optimization. Once we mount a Node to a View, its NodeRegion is not used anymore with RCTText being an exception, but it will correct itself automatically upon updateNodeRegion call. This patch allows the dead object to get garbage collected.
