Migrator stripped window.mixpanel inside mixpanel.js and replaced it just with mixpanel

Not really sure how/why but this can lead to very hard to track down errors

Hmmm, I thought we had removed the window stripping. And if we left it, I'm not so sure what it is useful for now?

Looks like it is still there, I may have messed this up in a refactoring... https://github.com/fivetanley/ember-cli-migrator/blob/master/lib/migrator-visitor.js#L69

I've had this with window.location as well
