On user creation, status is always 1 even if set to another value

[marc-farre]

Steps to reproduce:

Create a new user using https://marketplace.humhub.com/module/rest/docs/html/user.html#tag/User/paths/~1user/post

In the POST data, set the status to 2:

"account": {
"username": "john.doe",
"email": "[email protected]",
"status": 2,
"tagsField": [],
"language": "DE",
"authclient": "local",
"authclient_id": "0123456789"
},

The new user has status 1.

This is because no scenario is defined on the User model before loading data.
And with no scenario, the status property is no returned User::safeAttributes().

So we need to set the scenario to User::SCENARIO_EDIT_ADMIN.

Problem: authclient and authclient_id are still not safe attributes with User::SCENARIO_EDIT_ADMIN.

Solution 1: in User::scenarios(), add 'authclient', 'authclient_id' to $scenarios[self::SCENARIO_EDIT_ADMIN]

Solution 2: create a new one such as User::SCENARIO_REST_API_EDIT_ADMIN.
And in User::scenarios() we could add:

$scenarios[self::SCENARIO_REST_API_EDIT_ADMIN] = ['username', 'email', 'status', 'visibility', 'language', 'tagsField', 'authclient', 'authclient_id'];`

@luke- #144 fixes the problem for the status property.

For authclient and authclient_id, see above (I did no test for my proposal).

@luke- This PR is related to the #140 which was done only for update action, so yes we need the same fix for create action as well.
