script: Launch script with correct action if last script call is terminated

Actions launched as resume will be used in a next script_call
if the new action is not marked as resume even when the previous
script run was already terminated.
This behavior is particular visible when a RA is received as
the script will run with action bound and not ra-updated
resulting into a wan6 interface down/up transition
