Revert "[PwdCheckAndroid] Add delay between check status header updates"

This reverts commit 849b3b5d.

Reason for revert: The assumption that the progress signal comes after
status signal was wrong, so this change causes a bug when re-running the
check.

Since this was meant to be merged, reverting + fix is easier than fixing
in a follow-up CL.

Original change's description:
> [PwdCheckAndroid] Add delay between check status header updates
>
> This CL adds a delay to status updates whenever multiple updates are
> notified to the mediator in a short time window.
> The minimum time interval between updates is set to 1 second.
>
> Bug: 1122026, 1092444
