m-default-nodes: clear all previous configured nodes if metadata changes to NULL

Browse source 
This will completely clear all the default nodes (current and previous ones)
if the configured metadata value has been set to NULL. This is needed so that
the 'wpctl clear-default' command completely clears all the default nodes state.
