Tests: Always verify whether QTemporaryDir/File creation succeeded.

Use QVERIFY2() with QTemporaryDir/File::errorString() consistently.
Attempt to catch issues like the below warning and follow-up issues.

QSYSTEM: tst_QFiledialog::clearLineEdit() QFileSystemWatcher: FindNextChangeNotification failed for "C:\Users\qt\_____aaaaaaaaaaaaaaaaaaaaaa"  (Access is denied.)
