router.history.previousLocation undefined at ensureConfigured() resolution.

I'm submitting a bug report

Library Version: 1.0.8

Operating System: Windows 10

Node Version: 6.10.2

NPM Version: 3.10.10

JSPM

Browser: Chrome 58.0.3029.110 (64-bit)

Language: JavaScript

Current behavior: router.history.previousLocation is undefined at time ensureConfigured() is resolved.

Expected/desired behavior: Since I'm getting my routes via http I need to ensure refresh is working properly. I have one fallback route which is used while I get my routes and build the router. I expected to use ensureConfigured() to navigate to previous location if it existed in case of refresh.
