fix: (killaura) always swing before the attack so jump-attacks pass Grim PacketOrderB

The swing (C0A) was skipped while airborne under FailSwing (only sent when onGround), but the attack (C02) still fired -> GrimAC PacketOrderB 'did not swing for attack' spammed on every jump-attack. The vanilla 1.8 order is swing-then-attack, so send the swing before every real attack regardless of onGround. FailSwing only swings on the miss path (which never issues a real attack), so this cannot double-swing.
