Auto-naming of uploaded `.ggs` project files is a bit confusing

Subject of the issue

Sample project: g3w-suite-demo-projects/projects/geocoding-control.qgs

Here's what I get: gli_acquatici_del_parco_geocoding-controlqgs.qgs instead of buildings_geocoding-control.qgs (among others)

That is:

• it should use group slug as filename prefix (eg. buildings)
• it shouldn't add other suffixes at end of the url/file (eg. -controlqgs.gqs, -controlqgs/)

Partially related to: https://github.com/g3w-suite/g3w-admin/issues/612 https://github.com/g3w-suite/g3w-admin/issues/542 https://github.com/g3w-suite/g3w-admin/issues/661

Steps to reproduce

1. change the name of an existing group

2. upload the sample project in there

3 auto-generated filename is: gli_acquatici_del_parco_geocoding-controlqgs.qgs
