Can this be a robolectric test?  We don't seem to be needing any native code or
really any of the chrome activity stuff, so it would be awesome if we could use
non-instrumentation tests for these.

We need to grab the assets for each test. As soon as we do anything involving
strings, icons, and other assets we can't use robolectric. It's not that we need
ChromeActivity more like we need the assets that come with it. I've tried to do
robolectric in the past and couldn't get it to work nor could I find any
examples that call any sort of Chrome-like manifest :c.

We might be using an older version of robolectric or we haven't configured it
correctly /fully, but it "seems" like this should be supported:

http://robolectric.org/configuring/ (look for Configure Resource and Asset
Paths).
