test: await async render in AddToCollectionModal collection-name assertion

FE-2's CancellableLoader hop renders the list one microtask after the test's
fixed tick budget; switch getByText -> findByText (async retry). Fixes a
regression merged in ac5641b (FE-2 landed without running this component test).
