Tests: Fix warnings about ignoring return value of QTest::qWaitForWindowExposed()

Fix warnings like:
../shared/particlestestsshared.h: In function 'QQuickView* createView(const QUrl&, int)':
../shared/particlestestsshared.h:64:33: warning: ignoring return value of 'bool QTest::qWaitForWindowExposed(QWindow*, int)', declared with attribute nodiscard [-Wunused-result]

by checking the return and adding some handling.
