Split some multi-snapshot tests to make blessing easier

When a snapshot test fails, it only emits a `.pending-snap` file for the first
snapshot assertion that actually failed, because subsequent assertions aren't
executed. That makes it cumbersome to re-bless tests that contain multiple
snapshot assertions.
