backends: Disconnect MetaInputMapper signal connection on device dispose

Browse Source 
This signal may be left dangling when disconnecting a device, and be executed
later on if the device is connected again, and mapped to other output. Make it
sure the signal handler is disconnected when unplugging the device.
