Subject: [PATCH] input-context: look for __inputMethodExtensions at the
 parents too

Look for `__inputMethodExtensions` custom property recursively upwards
the parent tree. This is useful when a QQuickTextEdit is wrapped inside
another QML component and application doesn't have access to the
QQuickTextEdit itself.
