wasm: Don't suppress exceptions during main()
If there's e.g. an infinite loop during main() that
would previously result in a blank page, but not error
message. The expected case is that we would get a RangeError
exception, but that exception never reaches the catch
handlers in qtloader.js.
Work around this by setting noInitialRun, followed by
calling main manually. We then need to handle the case
where the app.exec() workaround throws, which should
not trigger an error.
Pick-to: 6.7
