Fix the Safety Center Status showing logic to cover edge cases

In old logic it was possible to end in a state where refresh is not in
progress with a request to continue scanning animation, rendering the
first frame of scanning animation instead of the final status icon.
Event sequence for this case:
1) receive initial refreshing SafetyCenterData with Severity Level A
2) wait until scanning animation is running in loops
3) do not receive any refreshing SafetyCenterData with Severity Level B
4) receive final non-refreshing SafetyCenterData with Severity Level B
