Fixed crashes relating to SVG icons.
Creating a second QFactoryLoader for the same plugins seems to trigger
an unload of the plugins loaded by the first factory loader. The
QIconEngine created by the SVG icon plugin thus gets an invalid virtual
table pointer, which causes a crash when attempting to call any virtual
function in the QIconEngine (pixmap(), the virtual destructor, etc).
Reusing a single QFactoryLoader instead fixes the crash.
Task-number: QTBUG-30496
