Mantis bug #5123: Toggle break on enter cannot work in 3.9-7061

Use changeset 2 for another/better fix to this issue; to remove the 
"class" message send.
Otherwise when setting a breakpoint on a method, instead the class 
method gets updated with the breakpoint; and setting a breakpoint on a 
class method results in the metaclass being updated!
