Issue title: Component error: when using double forward slash in JsCode
 Issue body: I have encountered a when used AgGrid with `allow_unsafe_jscode` to `True` and passing `cellRenderer` for one of the Column 

```
Component Error
`` literal not terminated before end of script
```

I am constructing a custom anchor tag based on `params.value` and using `https://` there was resulting in error 

I have escaped forward slash i.e. `https:\/\/` to fix the issue,

I was wondering if this can be handled more elegantly in the component itself ? Thanks
used to work in pre version. 

(have switched from `0.2.3` where it was working to `0.3.2` so not sure when it was broken in between)

 Comment 0: Should be fixed in 0.3.3
