The fields of ROUTE message were not read from the input buffer, thus the input buffer got corrupted. Sending a new message to the server would result reading the remaining fields from the buffer, which means reading some values instead of message signature. Because of this unmet expectation, Memgraph closed the connection. With this fix, the fields of the ROUTE message are properly read and ignored.
