LibJS/Bytecode: Fix bogus program termination after try with catch

Browse source 
For `try` statements with a `catch` clause, we were generating *two*
"next" blocks. This meant that not throwing an exception would cause
execution to stop.

Fix this by using the "next" block pointer for the try "entry" and
"handler" blocks.
