indianwhocodes dab7192e1e tests: fix FakeSwift HEAD with query param 
The existing FakeSwift implementation already supports using registered
GET responses for GET requests with a query param.  It also supports
using registered GET responses for HEAD requests (if they either both
had the exact SAME matching query params, or both did not have ANY query
params).  But it did not support using registered GET responses w/o
query params for HEAD requests with a query param, even though a GET
with the same query param would work.

This change makes it a little more consistent: any client or test that
makes a GET request, should be able to make a similar HEAD request and
expect consistent response headers and status.

This test infra improvement is needed as we're going to be extending
test_slo with a bunch of tests that assert consistent response headers
for both GET and HEAD requests w/ new query params.
