Fix incorrect setup in 'tag' query var test.

The test, introduced in [33724], was intended to demonstrate the behavior of
`example.com?tag=foo` routing. But an error in the test setup meant that a
URL-encoded tag object was being set as the value of 'tag'. Due to a quirk in
the way that `parse_request()` parses query vars, an object value for 'tag'
would inadvertently produce correct results in certain cases. But it's not a
usage we actively support, and it's not what was meant to be tested.
