Title: Fixed TryStatement AST reformat when using acorn

As shown in http://mzl.la/1hkKgkE there is no property named
`handlers` in the TryStatement node, but one named `handler`.
Previously, a TypeError (cannot reach `[0]` of `M.handlers`) exception
was thrown when using `uglifyjs` with the `—acorn` switch.
