[BUG] AdminApiClient unable to properly define scopes

[huelsmc]

Current Behavior

When using "scopes" inside credentials when building the adminApiClient there is missing a transformation to scope as it's expected by League when using PasswordGrant

$client = $this->validateClient($request);
$scopes = $this->validateScopes($this->getRequestParameter('scope', $request, $this->defaultScope));
$user = $this->validateUser($request, $client);

The client is therefore unable to apply any other scope than the default scope defined (write admin)

Expected Behavior

When defining scopes while using grant_type: password it should either be converted to a proper "scope" key before request is actually made or the type should be adjusted to just use scope as expected from API.
