PPSI does not copy peer to activePeer when in slave mode

When WRS or WRPC is a slave wr_mon/monitor does not display peer's MAC. possible fix is to replace

if (bmc_add_frgn_master(ppi, &frgn_master) != NULL);

with

if (bmc_add_frgn_master(ppi, &frgn_master) != NULL);
        memcpy(ppi->activePeer,ppi->peer, sizeof(ppi->activePeer));

in the listening_handle_announce function (file proto-standard/state-listening.c)

Looking at the code bmc_add_frgn_master is called in few more places. TBD if other places should copy peer to activePeer.
