1. Added null/empty jQuery check & default top val …

   Based on this error I get when running GitBook 3.2.2:
   
   ```
   Uncaught TypeError: Cannot read property 'top' of undefined
       at a (theme.js:formatted:5276)
       at HTMLLIElement.<anonymous> (theme.js:formatted:5315)
       at Function.each (theme.js:formatted:784)
       at de.fn.init.each (theme.js:formatted:694)
       at HTMLDivElement.l (theme.js:formatted:5313)
       at HTMLDivElement.dispatch (theme.js:formatted:2468)
       at HTMLDivElement.m.handle (theme.js:formatted:2400)
   ```
   
   Accordingly, I've added
   
   # A null check to the `while` loop of `getElementTopPosition`
   # An empty jQuery element check to the `while` loop of `getElementTopPosition`
   # Sensible defaults should the call to `$el.position().top` in `getElementTopPosition` fail
