Unable to reconnect with server after 2.4.1 update

[gjhommersom]

Describe the bug
As of version 2.4.1 (and up to 2.4.4 of time of writing) the Connection.reconnect() method no longer works.

To Reproduce
Simplified version of our code:

while(true){
  if (!connection.isOpen()){
    connection.reconnect(false);
  }

Expected behavior
There are 2 bugs in the code:

1. the connect method fails because the socket field is never set to null so the connectAsync call will always fail.
   

   rethinkdb-java/src/main/java/com/rethinkdb/net/Connection.java

   Lines 125 to 128 in efd7c0a

   	public @NotNull CompletableFuture<Connection> connectAsync() {
   	if (socket != null) {
   	throw new ReqlDriverError("Client already connected!");
   	}

2. The reconnect method must be given a value of false. If a value of true is used a query is attempted that will fail because it has no active connection.
   

   rethinkdb-java/src/main/java/com/rethinkdb/net/Connection.java

   Lines 447 to 450 in efd7c0a

   	protected @NotNull CompletableFuture<Response> sendQuery(@NotNull Query query) {
   	if (socket == null || !socket.isOpen()) {
   	throw new ReqlDriverError("Client not connected.");
   	}
