LibJS: Leave unwind contexts on enter of finally blocks in Bytecode

Browse Source 
Before we were doing so while exiting the catch-block, but not when
exiting the try-block.
This now centralizes the responsibility to exit the unwind context to
the finalizer, ignoring return/break/continue.
This makes it easier to handle the return case in a future commit.
