Handle when elements they lose their ref inside TouchScrollable

[Nedomas]

Posting it here just to check if anybody else had a problem with disappearing refs inside TouchScrollable.

An error with undefined this.scrollableArea in this.scrollableArea.removeEventListener started happening when I've started using React Suspense with React Router DOM. In certain scenarios if you load a route with Suspense on it, TouchScrollable sometimes loses this.scrollableArea value.

Not sure if there's something esoteric happening inside Suspense or there's something else - could not figure out. Was wondering if anybody else had a similar problem?

The diff here is just something that fixed my issue, but might be introducing some other problems later down the road.

Anyways - thanks for an amazing package!
