If GPKG has more than one layer it complains no table is specified

[antoniolocandro]

Import a GPKG with more than one layer the following popup shows but there is no option to select which table, so it seems only single layer GPKG are supported

Ideally when adding a GPKG with multiple tables a user would be able to select all the tables that they want imported to keep track off

As a sample the world_map.gpkg shipped with QGIS may be used
