avm1: Set target clip to None if target is an undefined object

SetTarget currently sets the target clip to the base clip if the
target passed to tellTarget() is an undefined object. This causes
goto's to run on the base clip in Ruffle, when Adobe Flash Player
does not run the goto's at all.

Fixes #12389 and #12390

avm2: Preserve attribute flag when filling lazy multiname with QName

Fixes #12570
