Some IME implementations do not produce composition strings, and their users have come to rely on the cursor that conhost traditionally left on until a composition string showed up. We shouldn't hide the cursor until we get a string (as opposed to hiding it when composition begins) so as to not break those IMEs. Related to #6207. Fixes MSFT:29219348
