Revert "added try/catch block that ignores exceptions due to empty document.applets[...] array"

This reverts commit c7f4bc9ce07a0a4ad559237355e68dfbce25a3ff.

Instead we will just wrap eval(sectionContext) in the try/catch block
since wrapping the dynamic code with try/catch doesn't solve the problem
because it doesn't get eval'd until later.
