throw exception InvalidArgumentException during validate scheme

[ArtsiomBruneuski]

Description

Fixed Issues (if relevant)

1. Communication's component validator does not propagate exceptions, obscuring the cause of the error #14555

Manual testing scenarios

A schema class:
class Dummy {
private $foo;

public function getFoo() { return $this->foo; }
public function setFoo($foo) { $this->foo = $foo; }

}
Communication configuration (communication.xml):

Run validation for communication configuration. It can be done either automatically if you're using Magento EE, or can be done manually by calling into Magento\Framework\Communication\Config->getTopic("foo_topic")
