Tobias FrölichandGitHub 1a529e9d5d fix(gui): expand tildes for subdir check (fixes #9400) (#9788)
### Purpose

This closes #9400 by always expanding tildes when parent/subdir checks
are done.

### Testing

I tested this by creating folders with paths to parent or subdirectories
of the default folder that include a tilde in their path as shown in the
attached screenshots.
With this change, overlap will be detected regardless of wether or not
tildes are used in other folder paths.

### Screenshots

Default Folder:

Newly created folder (parent directory in this case)
