[DO NOT MERGE] Fix the blank space on contextual card loading timeout

Root cause:
Sometimes loading contextual cards exceeds 1 second and a timeout
expires. In the past, we used the timeout in order not to update
homepage UI and to avoid screen scrolling. But we've introduced a
mechanism of card space pre-allocation to avoid flickering, so when the
timeout expires, the pre-allocated space will be always blank.

Solution:
Display a card on timeout if the one-card space is pre-allocated.
