Title: Fix flaky acceptance test.

@jzoldak please review.

Reason:
There are two buttons in Studio course assets when there are no files in assets: in the middle of the page and in the right upper corner.
In the middle of acceptance tests, manual testing shows, that button in the middle is not clickable.
That's why css is changed.
