Pass checks argument to sensei_can_user_view_lesson filter

[merkushin]

Resolves #7630

In the original issue, the Preview setting didn't work if the user's access expired.

Here, we pass our initial checks to the filter to allow making a final decision inside hooks.

LGTM!
If you decide to apply the change I suggested, feel free to merge after tweaked since it's very small and not super relevant.
