[GUM] BUG: New project created doesn't save in Load Recent

[kaltinril]

When you create a new GUM project, it seems to save the file, and you can edit things and it saves the state as you add objects and manipulate values. However, if you close the editor, and later open it back up, it doesn't show in the Load Recent history. The only way to get something.

Steps to reproduce:

1. Open Gum.exe (2024.8.20.0)
2. Create a new project
3. Save the project to create a file
4. Add something (screen + container + circle)
5. Close Gum.exe (Do not save, it seems to auto save)
6. Open Gume.exe
7. Notice that your project is not in the Load Recent list, nor is it in the Load Recent "More" list

Steps to get it into the Load Recent list:

1. Open Gum.exe
2. Click Load Project
3. Select your project that isn't in the Load Recent and click open
4. 2nd issue: Go to File > Load and notice your project doesn't show here
5. Then go to More and notice your project is in the MORE list
6. Now when you close and open GUM it will show up in the File > load list, and the File > Load > More list
