  Fix erroneous hangup extension execution
  
  ast_spawn_extension behaves differently from 1.4 in that hangups and extensions
  that do not exist do not return an error, whereas in 1.6 it does. This is now 
  taken into account so that the AST_FLAG_BRIDGE_HANGUP_RUN flag gets set
  properly.
  
  (closes issue #16106)
