Text gets duplicated in Find References if there are multiple classifications

[jasonmalinowski]

Steps to Reproduce:

0. Be a part of the enhanced colors flight.
1. Copy this into a source file:

        const int Foo = 42;
        const int Bar = Foo;

2. Invoke Find References on Foo.

Actual Behavior:

Observe the "BarBar". Since we now have two classifications on this span, we aren't handling it well. Also note the span for Foo (which should be highlighted as the thing we're search on) is all screwed up.

This is fallout of the enhanced colors work. @JoeRobich any chance this is a dupe?
