[3.2.12] Class References finds methods that don't actually reference class

[LisaAlmarode]

This is a followon issue to #513.

If you have a method that has the same name as a class, and you browse references to the class, you get this method, even though it doesn't actually reference the class.

My class name is Artichoke

and has the methods:
Artichoke
^self class
myOwnSelf
^Artichoke
test
^self Artichoke

Browse Class References returns the second two methods; the last one is not correct.

The base image query produces correct results:
