Sqlite, fix test_sqlite_add_column_in_transaction, failing due old monkey patch for mssql

  1) Error:
TransactionTest#test_sqlite_add_column_in_transaction:
ActiveRecord::ActiveRecordError: Called deprecated `ActiveRecord::Base.connection` method.

Either use `with_connection` or `lease_connection`.
