add missed method for InteractsWithConsole

[krwu]

There should be a method console() which returns an instance of Spiral\Console\Console.

After merge this PR, $this->runCommand can be used at any test method. Like:

    public function testInteractWithConsole(): void
    {
        $output = $this->runCommand('views:reset');

        $this->assertStringContainsString('cache', $output);
    }

This PR can Close #27
