Subject: [PATCH] QtWidgets: Use the default constructor of QString and append

Addressing a comment from the review of QTBUG-98434: instead of the
QL1S constructor use the default constructor and append "Path: "_L1.

With the QL1S constructor capacity == size == rhs.capacity and the
very next append is guaranteed to reallocate. In the other case the
capacity will grow according to the growth strategy.

Task-number: QTBUG-103100
