Extra superfluous edit-config RPC sent - Netconf-482
Extra superfluous edit-config RPC sent just prior to correct edit-config RPC for top-level lists
POST & PUT to certain top-level lists in a mounted device's model returns a 500 error via Restconf,
although in some cases (device-dependent) the config appears to have committed.
This problem first appeared in Boron-SR3, and continues in Carbon SR-1.
