Require "logger" before "active_record" in spec helper

ActiveRecord 6.0 / 6.1 reference the top-level Logger constant at
load time via ActiveSupport::LoggerThreadSafeLevel. If logger is not
required before active_support is loaded, requiring active_record
fails with:

  NameError: uninitialized constant ActiveSupport::LoggerThreadSafeLevel::Logger

Explicitly require "logger" first so the older Rails rows in the
per-Rails gemfile matrix (AR 6.0 / 6.1) can load the specs.
