Could not write TV input config to file
Hello, I'd like to ask, how can I solve this problem?

```
[12/10/2020, 07:08:03] [webostv] [LG TV] Error occured, could not write TV input config to file: [Error: ENOENT: no such file or directory, open '~/.webosTv/inputsConfg_388c50208dc7'] {
  errno: -2,
  code: 'ENOENT',
  syscall: 'open',
  path: '~/.webosTv/inputsConfg_388c50208dc7'
}
[12/10/2020, 07:08:03] [webostv] [LG TV] Error occured, could not write available TV inputs to file: [Error: ENOENT: no such file or directory, open '~/.webosTv/inputsAvailable_388c50208dc7'] {
  errno: -2,
  code: 'ENOENT',
  syscall: 'open',

}
```

I have a problem with inputs. I can't see the inputs, when the TV is OFF or after I restart homebridge I can't see last setup of inputs.

My code in config.json is:

```
{
            "devices": [
                {
                    "name": "LG TV",
                    "ip": "(secret)",
                    "mac": "(secret)",
                    "keyFile": "/var/homebridge/lgtvKeyFile",
                    "prefsDir": "~/.webosTv",
                    "pollingInterval": 5,
                    "volumeControl": "slider",
                    "volumeLimit": 100,
                    "channelControl": false,
                    "infoButtonAction": "INFO",
                    "inputs": [
                        {
                            "appId": "com.webos.app.hdmi1",
                            "name": "Set-top Box"
                        },
                        {
                            "appId": "com.webos.app.hdmi3",
                            "name": "Apple TV"
                        },
                        {
                            "appId": "com.webos.app.hdmi4",
                            "name": "PS4 Pro"
                        }
                    ]
                }
            ],
            "platform": "webostv"
        },
```


Thank you. :)
