minimal fix for issue 97

[Shakadak]

I think there is a more fundamental improvement that can be done to fix this issue by reviewing how we use Stream.resource, but this is the smallest change we can do to improve the situation right now

cf #97

Suggested change

	defmodule Issue97Test do
	use ExUnit.Case
	test "stream_tags doesn't hang when used with stream take on empty xml" do
	defmodule SweetXmlTest do
	use ExUnit.Case
	describe "stream_tags/3" do
	# c.f. https://github.com/kbrw/sweet_xml/issues/97
	test "should not hang when used with Stream.take/2 on an empty xml" do

While I do like the fact that this helps linking these tests to the issue raised to gain an understanding of the reason it was added, i think having a meaningful test module name might be better for overall comprehension and reading of test files.
Especially considering there are several ways of achieving the same results through other means; for instance, the commit itself already have that information. We could even put a link to the Github issue in the commit description, and / or even in a @doc or @docmodule attribute here.
