### Bug description
The OCC-Command `db:convert-type` seems to ignore the DB properties (type, user, host, database, port, password) provided through the CLI and instead operates on the database configured in `config.php`
I believe this may be related to the commit 79c4986 as this reworked the parameter handling in `ConnectionFactory.php`.
If I read this correctly, the default parameters are now always generated based on the system config instead of the passed arguments.
Running `db:convert-type --clean-schema` drops the tables in the "old" database.
### Steps to reproduce
1. Have Nextcloud 29.0.0 running with a MySQL database, and an empty PostgreSQL database
2. run `php occ db:convert-type --password=<PASSWORD> --port=5432 pgsql nextcloud_app postgres nextcloud` (note: the host `postgres` is a Kubernetes service name)
3. The command executes no matter if the Postgres Database is running or not, the command throws Constraint Violation errors in the table `oc_accounts`, I assume because it tries to migrate the content of the old database into itself.
