Regression: scan may lead to permanent crushing

[SeremTitus]

scaning in multiple projects can lead to crush and app does not open again,
it immediately crush when trying to open.
1.3.stable 1.4.stable

Reproduce by:
clone https://github.com/godotengine/godot-demo-projects
scan in with godots

While awaiting for the pull request to be merged, if encountering the issue, you can revert the changes manually in projects.cfg by deleting all the latest projects added by the scan. They should be below all your previous added projects.

Location of projects.cfg file:

• Windows: %APPDATA%\Godot\app_userdata\godots\projects.cfg
• macOS: ~/Library/Application Support/Godot/app_userdata/godots/projects.cfg
• Linux: ~/.local/share/godot/app_userdata/godots/projects.cfg

If you would like to go fresh and reimport your projects manually from the start, you can safely delete the file and open Godots again.

does this crash related to #153?

does this crash related to #153?

After my linked fix, Godots doesn't crash with the reproduction steps anymore, so we may assume yes.
