Package Layers Algorithm Not Honoring Save only selected features for Layers with no Selected Features

[ar-siddiqui]

What is the bug or the crash?

If no features are selected in certain layers, the package layer algorithm will save all features. This is not what a user would expect. In my use case, I have many layers in a project, I selected features from all layers for a small sub-area and want to export all selected features in all layers as separate layers in a GPKG. Package Layers algorithm would have worked if not for this bug.

Steps to reproduce the issue

1. Create two layers

2. Select features from one layer and no feature from the second layer
   

3. Run Package layers algorithm with Save only selected features checked
   

4. Resulting GPKG would have all features for layer with 0 feature selected

Supported QGIS version

• I'm running a supported QGIS version according to the roadmap.

New profile

• I tried with a new QGIS profile

Additional context

IMO for layers with 0 selection, no features should be saved or the layer not created at all.
