Fix doctrine:database:create failing without server_version for some connections

getDatabasePlatform() triggers a connection to auto-detect the server version when
server_version is not configured. Since the target database does not exist yet at
this point, the connection fails. Switch to getDriver() which identifies the driver
type without opening any connection.
