Connect/reconnect generates phony error during seqnum resync

Sequence -
1) Send order (Limit)
2) Drop connection
3) Order executes in series of parials
4) Reconnect
5) Sequence number resend/reset messages are exchanged interleaved with execution reports
6) The Application is passed the execution reports as if no error occurred

The final execution report is passed to the application, but a rejection is sent to the initiator complaining that Tag 122 is missing. Execution report is not required to have Tag 122 and the previous message received did have Tag 122.
This happens each time this test is repeated. Sometimes the last two messages preceding are execution reports and both are rejected.
