Quickstart Playground can crash Dev Home if the user saves a project into the same folder twice

[adrastogi]

Dev Home version

0.1401.495.0

Windows build number

10.0.26217.5000

Other software

OS Build Version: 10.0.26217.5000.amd64fre.ge_current_directadept.240509-1700
.NET Version: .NET 8.0.4

Steps to reproduce the bug

1. Generate a new project via Quickstart Playground
2. Save the project via the 'Save' button and pick a new folder for the generated assets
3. Click 'Save' again and pick that same location

Expected result

I don't think we've spec'd out exactly what we want the desired behavior here (I could imagine something like prompting the user if they want to overwrite the existing files, or giving an error and asking the user to pick a different destination if we don't want to support overwriting)

Actual result

Dev Home crashes.

Discussed internally and we will hold off on trying to get a fix in for this right now (ideally, we will have a proposal UX that we can implement for the 0.15 release). We think this won't be a common scenario, i.e., trying to save the same project on top of itself.
