The db_name parameter passed in command-line (-d) or in configuration file,
supports a list of database names separated by commas, in order to
preload them. The WorkerCron processes will also respect this list and only
connect to the specified database(s).
As of Odoo 9 the server also automatically initializes a new database
if the one passed via `db_name` does not exist or is not initialized.
This code did not properly handle multiple comma-separated value,
and created an unitialized database named `a,b` when db_name was set
to `a,b`.
