Problem with PTS address saving

[KKopyscinski]

Sometimes it's needed to save PTS address before it's resolved, for IUT to use it to identify connection. This was found in GATT/SR/GAN/BV-02-C, and regression is caused by https://github.com/intel/auto-pts/commit/df2c2710cd9ae0239dae1a6ba8983d714bf27467: set_pts_addr() call was removed from gap_connected_ev_

Maybe we should save flag if address is resolved:LeAddress = namedtuple('LeAddress', 'addr_type addr', 'resolved'), then by default: PTS_BD_ADDR = LeAddress(addr_type=0, addr='000000000000', resolved=False). And add flag to set_pts_addr, which may default to False and be True in gap_identity_resolved_ev_ (and same for LT2). That will allow to check if we are using resolved address when it matters
