No slave_status logging when using MySQL or SQLite

[RichieB2B]

When using the MySQLLogging or SQLiteLogging modules, only log types charge_sessions and green_energy are processed. Log type slave_status is completely ignored. I think it works though in the CSVLogging module (code check only, I did't actually test it).

I find the slave_status way too chatty to log to a database, so I'm not going to fix this. If it had worked I would have muted the topic anyway.

Also, log type slave_power is currently ignored by all logging modules.
