Fixe for "cannot call methods on sortable prior to initialization"

If the binded element is removed before initialization, the "cannot call methods on sortable prior to initialization" error occur.
This fix checks for the sortable data is stored on the element, and only call "destroy" if the data is present. 
Also, it clears the timeout, preventing the sortable to be created on an element just removed.
