[tor-commits] [tor/master] Rename node_has_descriptor() to node_has_any_descriptor()

commit 47163780c3682d881ad6e8044320a57fce439ea1
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date:   Mon Apr 16 11:51:02 2018 -0400

    Rename node_has_descriptor() to node_has_any_descriptor()
    
    Changing the name of this function should help keep us from misusing
    it when node_has_preferred_descriptor() would be more appropriate.
