Debugger: Fix AbstractPositionManagerTest

MockReferenceType can't be used anymore because the new DebuggerClassNameProvider requires much more from it.
The new SmartMockReferenceType implements methods such as nestedTypes() or allLineLocations() properly.

Also, as PositionManager can return more than one class, we should check if any of the classes it returned matches the pattern.
