gdbus-tool: Fix tab-completion for non-message-bus connections

Browse Source 
• `gdbus monitor` can’t work at all for non-message-bus connections,
   since it can’t subscribe to signals.
 • Other tab completions for names depend on the connection being a
   message bus connection, but we still need to print `--dest` (etc.)
   when tab completing them, even if we can’t print a list of
   available names.
