Minor UI issue

[bleutzinn]

On the plugin config dialog in the Generate and Presets tabs at the bottom the CLI command which uses the configured UI fields is shown.

When the Route field is empty the command adds a / by itself. However when a Route is entered which starts with a / the command shows not one but two slashes: //.

Just wanted to let you know.

Thanks! Sounds like a small tweak to the JS.
