Removing global document references (#1482)

Browse Source 
fix for options `recordCanvas: true`: 
* replace document.createElement with doc.createElement in rrweb-snapshot code
* Eoghan: add a regression test to prevent future accidental use of `document` instead of `doc`.  This test can be excised if a new feature can only be run in the browser and not in the jsdom environment
