{{Quickfixn}} Field 35 not found when connecting using FIX.5.0SP2

I found the problem, but I don't know if the cause is the FIX spec or the
QF implementation.

GenerateLogon does not add the MsgType field for the Logon
because FIX50SP2 does not have that message type.

FIX50SP2.Create(string beginString, string msgType) => switch ("A") results
in a message with no tag 35 which is then rejected by Session.SendRaw() due
to  message.Header.GetString(Fields.Tags.MsgType) => FieldNotFoundException.
