After calling destroy on initialized object it is not possible to initialize again.

[nikodemrafalski]

Repro steps:

1. $.smallipop({}, 'something');
2. $.smallipop('destroy');
3. $.smallipop({}, 'something else');
   Expected: hovering over element show smallipop
   Actual: nothing happens.

Root cause: destroy doesn't clean up its classes smallipop-initialized and smallipop from element.
When removed manually it's bac to normal
