Prevent swapping order of multiple buttons in CTA

[adamkudrna]

When there are multiple buttons or item actions in div.cta, they should always appear in the same order.

Currently it can be fixed like this:

.cta > .btn:not(only-child),
.cta > .item-action:not(only-child) {
    @media screen and (min-width: @grid-float-breakpoint) {
        float: none;
    }
}
