Move the jsdom emulation to after unexpected

This ensures that error messages from unexpected are 
syntax highlighted on ansi terminals, due to an "issue" in 
unexpected, where if first detects the DOM, then if not,
 attempts to check for an ansi terminal. Moving the order 
of the requires works around this issue.
