* Update ProjectLocator unit tests
* Update unit test:
Add a subfolder to reproduce issue where `endOfBranch` is called before the search has ended.
* Add missing `else` to prevent additional call to `endOfBranch`
* Simplify conditions by moving `if (element != null)` higher
* Replace `endOfBranch` by check at end of `startSearch`
