vty: fix vty->index for implicit go_parent_node 

After this patch, most vty_go_parent() functions are really obsolete, as
originally intended: A vty_go_parent() is only needed if the program
requires an action to run on VTY node exit.

vty_transcript_test.vty shows the fixed behavior.

For details, see preceding patch
"vty: show bug in implicit go_parent_node"
