Rewrote the bug561.sh test as the error_messages test that covers what was tested by the script as well as some new parts that were untested. This revealed a bug in the error messages where MaxScale always returns the database name in the error.

* Regression case for the bug "Different error messages from MariaDB and Maxscale"
|
|
*
|
|
* - try to connect to non existing DB directly to MariaDB server and via Maxscale
|
|
* - compare error messages
|
|
* - repeat for RWSplit, ReadConn
