Useless error message when depending on test that does not exist

[sebastianbergmann]

Reproducting example

<?php declare(strict_types=1);
use PHPUnit\Framework\TestCase;

final class Test extends TestCase
{
    /**
     * @depends doesNotExist
     */
    public function testOne(): void
    {
    }
}

Actual output

$ ./phpunit --verbose Test
PHPUnit 8.0.1 by Sebastian Bergmann and contributors.

Runtime:       PHP 7.3.2 with Xdebug 2.7.0rc1

S                                                                   1 / 1 (100%)

There was 1 skipped test:

1) Test::testOne
This test depends on "Test::doesNotExist" to pass.

OK, but incomplete, skipped, or risky tests!

Expected output

@epdenouden Do you think that this can be implemented?

[epdenouden]

@sebastianbergmann Yes and I can build it if you'd like. I've recently done work in that area, it's just one extra check near the @depends handling. Bubbling a nice error to the surface might take a bit more work, I'll check it out.

[sebastianbergmann]

Would be great if you could implement this.
