Repeated errors from modbus connection printed out after closing

After opening and closing a modbus connection, a number of errors equal to the number of requests sent while the connection is open are printed out.

Each error is formatted as follows

> QModbusDevice::ReplyAbortedError [Text] ReadReady_Coils 37 [Text]
> ReadReady_Coils "Reply aborted due to connection closure."

See the attached project to reproduce the error.
