Error: Database Selection in GMLAS Wizard not working

Environment

• Plugin version: 233e51d
• QGIS version: 3.22 LTR
• Operating System: Windows 10

Description

When trying to load a WFS in GMLAS mode the Database Selection in the Wizard is not working.

spatialite

When selecting a spatialite connection and selecting finish in the Dialog the Dialog just stops. I think this is because of a broken if condition in the ImportGmlasPanel.do_load() function. The last else just returns, if none database formats match. My proposed solution would be to default to a temporary spatialite db (same with no connection selected)

postgres

When selection a postgres connection I the Error shown below:

PR #238 fixes the issue with spatialite.
I didn't manage to find a solution for the postgres error.
