enum should be serialized with name and not default toString

`org.glassfish.jersey.client.proxy.WebResourceFactory.invoke(Object, Method, Object[]) ` uses the value as is, which defaults to using the `toString()` method which causes issues with enums when the `toString()` does not return the same value as the `name()`

This forces implementation to provide a `public static fromString(String x)` method.

Jersey Version: jersey-proxy-client-2.38.jar

Would it be possible to use the `name()` instead if the Class of the given value is an enum?
