Make sure that container is shut down when tests fail

[tomas-langer]

version 2.5.1: when a test @HelidonTest fails to start the container (such as when configuration is invalid for security), any further test classes annotated with @HelidonTest also fail to start with an exception:

java.lang.IllegalStateException: There is another builder in progress, or another Server running. You cannot run more than one in parallel

[tomas-langer]

Confirmed with 2.5.3.

To reproduce:
Create an extension, such as:

package reproducer;

import javax.enterprise.event.Observes;
import javax.enterprise.inject.spi.AfterBeanDiscovery;
import javax.enterprise.inject.spi.DefinitionException;
import javax.enterprise.inject.spi.Extension;

public class FailingExtension implements Extension {
    private void observeAdd(@Observes AfterBeanDiscovery add) {
        throw new DefinitionException("Failed");
    }
}

To the first test that gets executed in IDE, add the following:

@AddExtension(FailingExtension.class)

Now run all tests in package - the first test will fail correctly:

javax.enterprise.inject.spi.DefinitionException: Failed

The second test will fail incorrectly:

java.lang.IllegalStateException: There is another builder in progress, or another Server running. You cannot run more than one in parallel

The same is valid in main, will start fixing in main
