fix assert logic

XMLNode::~XMLNode uses interface method DeleteChildren(), which
iteratively removes the first child until the list is empty. Each single
removal performs additional checks and keeps _firstChild and _lastChild
links in a consistent state. This leads to a performance penalty.

The proposed patch solves this problem by iterating the list of the
children and directly destroying them without keeping links in a
consistent state.

The performance boost we gained on xmltest is:
- 3% for my laptop (x86_64)
- 9% for bananapi f3 board (riscv64)
