tests: Avoid accessing Qt statics at import time

With a Qt 6.7 developer build, the tests fail with:

    ASSERT failure in QtGlobalStatic::ApplicationHolder<QAS>::PlainType*
    QtGlobalStatic::ApplicationHolder<QAS>::pointer() [with QAS =
    {anonymous}::Q_QAS_qtlsbLoader; PlainType = QFactoryLoader]: "The
    application static was used without a QCoreApplication instance", file
    .../qtbase/src/corelib/kernel/qapplicationstatic.h, line 54

    Fatal Python error: Aborted

    [...]

    Current thread 0x00007c18bb3f3740 (most recent call first):
    File ".../tests/unit/browser/webkit/test_certificateerror.py", line 23 in <module>
