Project Manager: Fix hacky code for project rename

Instantiating a new ProjectSettings is *not* the way to go.
ConfigFile works just fine to read/change a single value.

Fixes memory leaks as the instantiated ProjectSettings was never freed.
Forbid doing this to prevent such problems.

Fixes #25661.
