Add @LooperMode LEGACY in tests that fail in PAUSED mode

[chggr]

Summary

The new Robolectric PAUSED LooperMode will become the default in new versions of Robolectric. We have ran all litho-it tests against the new PAUSED LooperMode and unfortunately some of them are failing. For these tests we need to explicitly specify the LooperMode as LEGACY to be future proof, so that they do not start failing when the default changes to PAUSED in the future.
