The only thing I changed here was this ternary. I change it to an early return to make this component more readable.

Rather than waiting for the loading state to go away and immediately asserting things, I updated this so that each assertion uses a find. This makes the test more resilient to inconsistent rendering behavior, which is what I suspect is happening in DatabaseResize
