Require logger in test setup

`ActiveSupport::LoggerThreadSafeLevel` depends on `logger`, but doesn't
require it explicitly prior to 7.1. In the real application, the `logger`
is likely required by other components so this is not an issue. But for
this gem's test setup, we need to require it explicitly.
