example of wrong collaboration diagram

For simple code:

namespace AAA {
	struct BB {
		AAA::BB* v1;
		BB* v2;
		
		std::list<AAA::BB*> l1;
		std::list<BB*> l2;
	};
}

and config:
	EXTRACT_ALL            = YES
	BUILTIN_STL_SUPPORT    = YES
	ALWAYS_DETAILED_SEC    = YES
	HAVE_DOT               = YES
	CALL_GRAPH             = YES
	CALLER_GRAPH           = YES

Doxygen 1.8.1.2 generate correct "collaboration diagram" - see attachment OK__structAAA_1_1BB__coll__graph.png.

Doxygen 1.8.6 generate wrong "collaboration diagram" l1 on diagram is AAA::AAA::BB type and not reference to BB struct - see attachment BAD__structAAA_1_1BB__coll__graph.png.


Problem is probably in normalizeNonTemplateArgumentsInString() function, or in used by it getResolvedClass() function.

Using
	result+=cd->localName();
instead
	result+=cd->name()
in normalizeNonTemplateArgumentsInString() function fix this issue, but don't resolve short name to full scope name (I don't know if it's a problem for other functionality of doxygen).
