Asserting invalid form should throw better exception

[rozsival]

Using FormAsserts::assertValidForm on an invalid form in a presenter test case results with Uncaught Nette\NotImplementedException: Object serialization is not supported by class <presenterClassName> in <projectRoot>/vendor/nette/component-model/src/ComponentModel/Component.php:298

Dependencies:

• nette/application: 3.0.2
• nette/forms: 3.0.2

It would be much clearer if the test failed the same way as with phpunit core asserts simply saying that asserting caused the failure.

Turns out it's not a form assert issue. This happens with any DIContainerTestCase failed assertion while phpunit.xml has processIsolation="true".
