self.span.end - 1 overflows if the NewExpression is generated in transformer and has no span, so self.span.end == 0.

@Boshen I'm not sure if this is the best way to solve the problem?

Similar to #7289. Check if `span.end` is 0 before doing `span.end - 1`, to prevent arithmetic overflow.

Also changed all checks to `span.end > 0`, just for consistency.
