Bug: Can not install/config the plugin 
### Describe The Bug

New install of plugin v1.12.5 and no config available

### To Reproduce

Install Switchbot-plugin the first time from Homebridge UI

### Expected behavior

click on configuration should show dialogs

### Relevant log output

```shell
A click on Plugin>Settimgs raises an error: Failed to load plugins config schema

Trying to Disable plugin (for testing) raises:
Failed to disable plugin: Http failure response for https://brdg.mydomain.de/api/config-editor/plugin/%40switchbot%2Fhomebridge-switchbot/disable: 404 Not found

I think the 404 is because of the %2F in plugin name, trying in the browser:
.../api/config-editor/plugin/%40switchbot%2Fhomebridge-switchbot  >> html Error: 404 Not Found
.../api/config-editor/plugin/%40any_letters  >> json status: 401 Unauthorized (which is ok for the test)
```


### Config for homebridge-switchbot

```shell
There is no code in config.json that contains 'switchbot'
```
