Regression Bug: JsonSerializationException for GetCurrentUserInformationAsync

See original GitHub issue

I have checked that the SDK documentation doesn’t solve my issue.
I have checked that the API documentation doesn’t solve my issue.
I have searched the Box Developer Forums and my issue isn’t already reported (or if it has been reported, I have attached a link to it, for reference).
I have searched Issues in this repo and my issue isn’t already reported.

Description of the Issue

Just upgrade from Box.V2.Core 3.22.0 to 3.23.0. A regression issue has bubbled up.

I can no longer call var user = await boxClient.UsersManager.GetCurrentUserInformationAsync(); without the a Newtonsoft deserialization issue. See Stack Trace below for further details.

Steps to Reproduce

internal BoxClient GetBoxUserClient(string userID)
{
    var boxConfig = new BoxConfig(this.ClientID, this.ClientSecret, this.EnterpriseID, this.PrivateKey, this.PrivateKeyPassphrase, this.PublicKeyID);
    var boxJwt = new BoxJWTAuth(boxConfig);
    var userToken = boxJwt.UserToken(userID);
    return boxJwt.UserClient(userToken, userID);
}

var boxClient = GetBoxUserClient("validuser@mydomain.com");
var user = await boxClient.UsersManager.GetCurrentUserInformationAsync();

Use the above code in version 3.22.0: Works. Use the above code in version 3.23.0: Exception thrown.

Expected Behavior

Not have an exception thrown.

Error Message, Including Stack Trace

Newtonsoft.Json.JsonSerializationException: Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'Box.V2.Models.BoxNotificationEmail' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.
