Improvement: limited timer digits to a proper value

As suggested here https://github.com/duckduckgo/zeroclickinfo-spice/issues/1327, I fixed ( limited ) timer value to a max that can be displayed without break the page's layout
Not that it's a big deal, but I would suggest a ternary here. Saves a few lines of code...

```javascript
return (time <= ###) ? time : MAX_TIME;
```
