Use getName instead of getSimpleName

This changes uses of `getSimpleName` to `getName`. The former throws
idiotic exceptions under Java 8, e.g., `getSimpleName` will fail if
used on a class inside an object.

This fixes a bug where any call to the `name` method of a custom
transform defined inside an object (or in an environment wrapping
things in objects like a REPL) will throw a malformed class name
exception. E.g., if you do this and run with `-ll info` or your custom
transform deletes annotations.
