Is there a reason to add this test?

[thorogood, 2012/08/28 00:04:04]

The reason for this is that it demonstrates that if a Web Intent handler
supports "*", it can accept all files, even those without extensions.

We weren't showing that this was the case through a test, and I added this
mostly to confirm this behaviour (as opposed to the alternative, which was that
a blank mime-type could not be matched by "*").
