Fix expectPropertyDoesNotExistException test

[simPod]

expectPropertyDoesNotExistException

$pair = new \Ds\Pair('a', 1); $pair->x;

PHP Notice: Undefined property: Ds\Pair::$x

I don't think the expected exception should be a PHPUnit exception to catch that PHP notice. We should take a look at why the OutOfBounds is not being thrown.

@rtheunissen I thought that throwing OutOfBounds is wrong in the first place. I always understood OutOfBounds to be valid in a situation such this $a = new Map(['a'=>1]); $a->get('b');

Here we're just accessing a property on an object that does not exist so that Notice seemed valid. I may be wrong tho.

[rtheunissen]

Accessing by property is a shortcut for $a->get('x') so I think we should keep those consistent.

@rtheunissen even on a Pair? I'd rather expect it on a Map. Feel free to close this.

Maybe this should not fully extend CollectionTest https://github.com/php-ds/tests/blob/master/tests/PairTest.php 🤔

[rtheunissen]

Good call, I think you're right. I'll merge this and come back to it to verify what's happening.

Thank you
