Title: Fixed a bug when the JsonSerializerSettings are changed

In my configuration method I change a ``JsonSerializerSettings``
```
JsonConvert.DefaultSettings = () =>
new JsonSerializerSettings
{
ContractResolver = new CamelCasePropertyNamesContractResolver(),
NullValueHandling = NullValueHandling.Ignore,
MissingMemberHandling = MissingMemberHandling.Ignore,
DefaultValueHandling = DefaultValueHandling.IgnoreAndPopulate,
TypeNameHandling = TypeNameHandling.None,
};
```
And with such settings I can register as many users with the same user name as I want.

This PR fixes the issue.
