* Fix relativeOrAbsolute bug with baseQDir in PathUtils.cpp
If `base` is `Absolute`, `baseQDir(base)` will point to the working directory. It will result in undefined behaviors.
To fix this, update relativeOrAbsolute to explicitly return an absolute path when the target base is Absolute. Also make baseQDir return QDir::root() for Absolute base instead of QDir(""), because the latter represents the working directory.
