Subject: [PATCH] Fix test race condition.

The test suite randomly fails with errors such as:

~~~
  1) Failure:
AutoloadingTest#test_autoload_lowercase [/builddir/build/BUILD/mustache-1.1.1/usr/share/gems/gems/mustache-1.1.1/test/autoloading_test.rb:17]:
Expected: Comments
  Actual: nil
~~~

This happens when `test_namespaced*` test cases are executed earlier
than the remaining test cases, because they are defining
`view_namespace` but not cleaning up afterwards.
