[BUG][C#] 7.12/13 enumeration converters not called

hi,
i'm having problems when my client try to read the following enum:

            "enum": [
                "NONE",
                "PROCESS_UNUSED",
                "TESTCASE_MISSING",
                "TESTCASE_FAILED_OR_PENDING"
            ]

after some debug, i found out probabily there is a bug in HostConfiguration.mustache:

_jsonOptions.Converters.Add(new JsonStringEnumConverter());
...
after some hundreds conveters.. there is the correct one:
...
_jsonOptions.Converters.Add(new ProcessWarningJsonConverter());

but ProcessWarningJsonConverter is never called, i have to comment out this line:
// _jsonOptions.Converters.Add(new JsonStringEnumConverter());

or (better probably) move it AFTER all the conveters.

after this change, it works as expected.
thanks,
David
