[feature request] A small "open project" dialog annoyance

[devloop0123]

Is your feature request related to a problem? Please describe.
When MusE is set to "open last project" in the global settings, and if the "projects" file is empty, then the "open.." dialog wants to create a directory /untitled inside the user's projects folder.

Moreover, if you choose to cancel that action, MusE doesn't open the user-defined projects base folder.

Describe the solution you'd like
The "open.." dialog should simply always open the user-defined projects base folder, and not ask to create anything, ever.

Edit: why would my "projects" file ever be empty or absent? I often delete it or its contents during troubleshooting.
