A test for the SenderLocator? 😉

+ but it does not rely on a `ContainerInterface` to find senders. Instead, it accepts the sender instance itself instead of its identifier in the container.?

Especially with the BC-break, it would be very good to have an explicit exception if this return value is not a SenderInterface. For example:
if (!$sender instanceof SenderInterface) {
throw new RuntimeException(sprintf('The sender instance provided for the message "%s" should be of type "%s" but got "%s"', $message, SenderInterface::class, is_object($sender) ? get_class($sender) : gettype($sender));

What's the reasoning for using an abstract class over a trait for this static method?

As it is used in SendMessageMiddleware, I think it's "better" like this.

For handler locators, we have a generic `HandlerLocator` class that takes a simple mapping instead of a service locator. The same did not exist for sender locators. So, this PR adds this possibility as well. That allows for something like this:
```php
new MessageBus([
new SendMessageMiddleware(new SenderLocator([
Message::class => new AmqpTransport($encoderDecoder, $encoderDecoder, $connection),
])),
new HandleMessageMiddleware(new HandlerLocator([
Message::class => new MessageHandler(),
])),
]);
```
