main: Use --replace semantics for org.gnome.Shell DBus name

Browse Source 
Previously (because I suck) we were ignoring the return value of
RequestName, and so we'd totally ignore the fact that we failed
to acquire the DBus name.

Make this consistent by using meta_get_replace_current_wm() and
if we're in --replace, actually replace immediately.
