Uncaught TypeError: Cannot read property 'destroy' of undefined

[kankaristo]

I started getting this after updating the package to 0.21.0.

1. Open a file
2. Close the tab
3. Error

Atom Version: 1.0.0 System: Ubuntu 14.04.2 Thrown From: multi-wrap-guide package, v0.21.0

This seems to have gone away after restarting Atom...

I guess the old version was still somehow active after updating to the new version. I've had this happen with some other packages as well, producing some really weird bugs.

I'll close this and report back if it happens again. :)

Just in case I added undefined guards for the destroy calls. Hopefully it won't happen again :+1:
