ASAN crash in bluez5-device.c:impl_clear
When bluez5-dbus.c:device_free occurs, bluez-monitor should probably free the SPA handle, as otherwise bluez5-device.c:impl_clear will get called later on with this->bt_dev referring to an already freed object.

(I'll have time to look at this only later...)
