Report polling test temporality (#325)

So the test before sometimes sent the report *before*
the protection (that is used to check whether we have received
the report) was registered.
This of course meant that we didn't ever receive the report from
the perspectivee of the test.
This PR should now mean we always send the report after
registering the protection.
