Small grammar fix in pluck description
Correctly determine if migration is needed.

This method would assume that if last migration in the migrations
directory matched the current schema version, that the database was up
to date, but this does not account for new migrations with older
timestamps that may be pending.

Use the released beta of i18n
Add option to stop swallowing errors on callbacks.

Currently, Active Record will rescue any errors raised within
after_rollback/after_create callbacks and print them to the
logs. Next versions of rails will not rescue those errors anymore,
and just bubble them up, as the other callbacks.

This adds a opt-in flag to enable that behaviour, of not rescuing
the errors.
    Example:
      # For not swallow errors in after_commit/after_rollback
      config.active_record.errors_in_transactional_callbacks = true

[fixes #13460]
No need to point to arel and i18n master anymore
