on iOS, a BLE device scan should return advertised name if set

Currently a device scan returns the name the ble stack thinks is the best name for a device. This name is cached and may change after a first connection has made to the device. From a developer point of view this name is not predictable.
So my suggestion is to return the advertised name if found in the advertised data, if not fall back to the name the ble stack gives.
Until the scanning api has been fixed (returns either a dictionary or the raw bytes of the advertised data) this is the best way to handle devices names
