`inlineToolbar` always show convertTo, inconsist behavior with config value, and cannot be removed

### Describe a bug.

```js
const editor = new EditorJS({
holder: 'editor',
tools: {
paragraph: {
// built-in inline tools: link, bold, italic
// disable inline tools: false,
inlineToolbar: ['bold', 'link'],
},
},
})
```

### Expected behavior:

convertTo should also follow `inlineToolbar` config, which control it show or hide.

### Screenshots:


As you see, it even show when no convertor available.
