Types of changes

• [x] Bugfix (non-breaking change which fixes an issue)
• [ ] New feature (non-breaking change which adds functionality)
• [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected)

Description of Change

This fixes a regression that happens as a result of earlier dev/7.6.x webpack changes. As of dev/7.6.x, webpack programmatically finds a project's settings.py file. This breaks if there's a folder that is visited earlier in the recursion that also has a settings.py file.

Issues Solved

Closes #10989
