LibJS/Bytecode: Do not unwind eagerly after throwing Await

Browse source 
If an exception was thrown while evaluating the argument of an `await`
expression, we should jump to the continuation block instead of eagerly
rejecting the caller async function.

This restores the behavior prior to the addition of the separate `Await`
instruction in d66eb4e3.
