sim: Fix the Ticked class constructor's event wrapper.

This uses a "name()" method which is not defined by the Ticked class,
and isn't a global method. This was probably originally supposed to be
the name() method of the Serializable class that Ticked inherits from,
but a while ago that was removed. It's not clear how this has been
compiling.

Instead, use the name() method of the ClockedObject which is the first
constructor argument.
