[PATCH BlueZ 3/3] Fix not showing name if first EIR has no name info

[Anderson Lizardo <anderson.lizardo@openbossa.org>]

Some devices may not advertise their name right on the first EIR data
sent (e.g. LE devices where name is set on either advertises or scan
responses, but not both). Given that the "found devices" cache does not
refresh the name on each EIR received, the UI may never show the name
during a discovery session.

This fix improves the Discovery UI by showing names immediately as they
are received. This works by emitting DeviceFound signals when the name
is received, even if RSSI stays the same.

Further discovery sessions will use the stored complete name, as usual.
