Fix handling of the ROUTE Bolt message (#475) 
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.
