[doc] Repository method count does not exist

[mcorteel]

The documentation references a convenience method of entity repositories named count.

Like this comment on stackoverflow states, it would be a great addition to the EntityRepository, but it doesn't actually exist (reference).

@mcorteel that method is definitely available for 2.6 but probably not for 2.5.x

[mcorteel]

Then I think it should be mentioned in the documentation. Shouldn't it?

Fairly sure that those docs aren't referencing the correct branch... To be checked in https://github.com/doctrine/doctrine-website-sphinx, I suppose.

Is this still an issue? As far as I can tell the docs are not referencing any branch directly (via a link or some sorts).

Would an acceptable fix for this to add a line to the current docs that the count method has been added in 2.6 suffice? I.e.,:

New in version 2.6.

Additionally, you can just count the result of the provided conditions when you don't really need the data:

    <?php
    // Check there is no user with nickname
    $availableNickname = 0 === $em->getRepository('MyProject\Domain\User')->count(['nickname' => 'nonexistent']);

[mcorteel]

Yes, that would fix it!
