Default Don't display the state of the newly added map during addition in the daemon and don't switch groups.

Hi Konrad,

A previous commit mass-changed #ifdef DAEMON to check for 'mpp->waiter'. Unfortunatly
when the 'domap' function is called with ACT_CREATE in the daemon, the mpp->waiter is not
set, hence the multipath client mode logic is choosen. Fixing this triggers another
issues which is that newly added path via ACT_CREATE won't have their waitevent thread
created as the caller checks mpp->action (which changed to ACT_NOTHING) and won't
start the thread.

Nice. Far cleaner fix. But you forgot this:
