Missing DEFINES edge for templated methods

[peckto]

For templated methods, the definition is not connected to the declaration.
This might also have side effects to the CallResolver when resolving calls to such methods.

Example:

template <class T>
struct B {
    void foo();
};

template <class T>
void B<T>::foo() {
}

struct A {
    void foo();
};

void A::foo() {

}
