Remove sleep from dragAndDrapThought.ts test

[raineorshine]

Continuation of #2110

dragAndDrapThought.ts - This sleep is needed so the notes have time to update after dropping. I made it so the sleep call only fires on drop, which means it only applies to a subset of the tests. Obv we can optimize this and probably get rid of the sleep altogether but, at this point, we're going to get more speed increases by splitting the drag and drop tests into two separate files that run in parallel.
