Fix auto completion for the case when template parameter should be
found somewhere of scope of template instantiation declaration.
Example:
struct A
{
void foo();
struct B
{
int b;
};
};
template<typename T>
struct Template
{
T* get() { return 0; }
T t;
};
void A::foo()
{
Template<B> templ;
templ.get()->//no autocompletion
templ.t.//no autocompletion
}
