Compatibility with Humhub 1.14

[marc-farre]

Since Humhub 1.14, I have: Calling unknown method: humhub\modules\user\components\User::canDeleteAccount()

This is due to: https://github.com/humhub-contrib/legal/blob/master/views/page/confirm.php#L44 and https://github.com/humhub-contrib/legal/blob/master/views/page/update.php#L47

Yii::$app->user->canDeleteAccount() should be replaced with Yii::$app->user->getAuthClientUserService()->canDeleteAccount().

But I haven't find any mention of this on https://docs.humhub.org/docs/develop/modules-migrate#version-114

@funkycram Oh, I overlooked that use. I have now updated the docs, temporarily re-inserted the method in the core and prepared a PR for the Legal module.
