Boxes: drop RHBZ #1692972 workaround, fix for
RHBZ #1692972 was fixed long ago, so we don't need to worry
about that any more. But this test failed on the recent F31 live
respin compose because it was changed to assume the tutorial
would appear on startup, which only happens on F32+. To make the
test work on F31 respins, let's handle both paths. Once F32 is
stable we can drop this as we won't run the test on F31 any more
after that.
