QLineEdit: ignore key release events

Browse Source 
Amends 55fe46fd58c73a7a22374694a1b45ec2a0e6fdc5. Before that change,
key release events were ignored as the QLineEdit::event reimplementation
continued to call QWidget::event, and as QLineEdit didn't override
keyReleaseEvent, the default implementation in QWidget got called to
ignore the event.

Restore that behavior by explicitly calling the QWidget implementation
after updating QLineEdit-specific states, and add a test case.

Fixes: QTBUG-114654
