Bug Report

Hello. I would like to report a bug in the latest version of Headroom.js. The problem is that in rare cases the destroy method can be called before scrollTracker has been initialized in line #42 due to putting it in the setTimeout callback which is not canceled when destroying the headroom instance.

Reproduction: https://jsfiddle.net/d20mxrbz/1/
