Is your feature request related to a problem? Please describe.
Yes. Currently, when attempting to create a team using a name with few letters (e.g. "ab"), the frontend only returns generics error messages, like below:

Inspecting the network tab, the actual error can be seen:

// POST ocs/v2.php/apps/circles/circles
{
    "ocs": {
        "meta": {
            "status": "failure",
            "statuscode": 400,
            "message": "Circle name is too short"
        },
        "data": []
    }
}

Describe the solution you'd like

Would be nice to return a more descriptive message to the user on frontend, so he knows what exactly is going on and what has to be changed.

Additional context
lib/Controller/LocalController::create() is the method reached by POST ocs/v2.php/apps/circles/circles endpoint.

Start at lib/Controller/LocalController::create(), which handles POST ocs/v2.php/apps/circles/circles, and trace how the frontend displays its response. Reproduce team creation with a name such as "ab" and compare the generic frontend message with the returned "Circle name is too short" error. Done means the frontend tells the user what must be changed.
