Repeat call multiple times leads to rpc to freeze

[luizstacio]

Using the code below;

Receiver

const rpc = new RPC({
 target: window,
 serviceId: 'my-service-id'
});

rpc.expose('myMethod', (a: number) => a);

Sender

const rpc = new RPC({
 target: window,
 serviceId: 'my-service-id'
});

rpc.call('myMethod', 1); // returns ok
rpc.call('myMethod', 1); // returns ok
rpc.call('myMethod', 1); // stop returning
rpc.call('myMethod', 1); // stop returning
... any other call will not return...

Debugging, I notice the issue happens because the this.callCounter sent on the call is one count above the this.lastSequentialCall.
