Ensure default system take wal_data_dir into account. #250

Right now it always defaults to the main Ra data dir.

Are the value identical or can the path change for existing installations?

That is a good question. If a system has wal_data_dir set already it will use a different directory. But this issue would also have been there in reverse for anyone with wal_data_dir set that upgraded from RabbitMQ 3.8 to 3.9.
